Search Capabilities

Integrated Index Searching

Searching for a Chemical

1. Click the Integrated Index link on the left side of the initial Corporate Solutions screen.
2. Enter the search term(s) in the Search Text box. Please Note: It is not necessary to enter the entire word, phrase, or number, except in the case of a CAS Number. Simply entering the first few letters or numbers will bring up matches for those characters, and you can scroll up or down in the list to find the exact match you want. When searching by CAS Number, you must enter the complete and accurate CAS Number. Entering an incorrect CAS Number will bring up an error message. However, even when the correct CAS Number is entered, that substance may not be in the ChemKnowledge® System.
3. From the Search Type drop-down list, select the type of search desired (i.e., Plain Text, CAS Number, etc.).
4. Click the Search button.
5. Search results most closely matching the search term(s) are presented. Select the desired item to reveal a list of all databases containing the search term(s).
6. Select the desired database to reveal the document outline.
7. Select a section from the outline to view a specific portion of the document.

Free-Text Searching

Search Rules

•Multiple consecutive words in the Boolean Search Boxes are treated as a phrase; they must appear in the same order within a matching document.

•Search terms are not case sensitive -- you can type a search term in uppercase or lowercase.

•You can search for any word except "noise" words (this includes common words such as a, an, and, as, and so on), which are ignored during a search. A complete list of noise words is available for review.

•"Noise" words are treated as placeholders in phrase and proximity searches. For example, if you searched for “right to know”, the results could give you “right to know” and “right and know”, because to is a noise word.

•Punctuation marks such as the period (.), colon (:), semicolon (;), and comma (,) are ignored during a search.

•To search for a word or phrase containing quotation marks, enclose the entire phrase in quotation marks and then double the quotation marks around the word or words you want to surround with quotes. For example, “Hazardous materials OR ““Haz-mat””” searches for Hazardous materials or “Haz-mat”.

•You can use Boolean Operators (AND, OR, and AND NOT) and the Proximity Operator (NEAR) to specify additional search information within a single search box (only within the Advanced Search).

•The Wildcard Character (*) can match words with a given prefix. The search term esc* matches the terms “ESC,” “escape,” and so on.

A free-text search allows you to use words or phrases to pinpoint the information you need. Choose operators such as and, and not, or, and near.

1. Click the ChemKnowledge® Free Text Search link. The initial page upon opening a ChemKnowledge® free text search is a simple search.
2. Enter a search term in the first box.
3. Select an operator, or leave the default and.
4. Enter additional search terms in the following boxes (you may enter up to five additional search terms - only one search term or phrase per box).
5. To narrow your search, scroll down to the Search In: table to select specific databases. Click the checkbox next to the specific database you want to search (you may select more than one database). Please Note: LOLI^® can only be searched using the Integrated Index feature.
6. Click Search.
7. Search results identify all documents in the specified databases containing the search terms within the body text. Click the hypertext to access document outline and text.

Use the advanced search option to facilitate long, complex Boolean searches. Click the Advanced button on the initial ChemKnowledge® Free-Text Search search screen to access this option.

1. Enter search term(s) and operator(s) in the In Title: or In Entire Document: search boxes. Continue adding as many search terms and operators as necessary.
2. To narrow your search, scroll down to the Search In: table to select specific databases. Click the checkbox next to the specific database you want to search (you may select more than one database). Please Note: LOLI^® can only be searched using the Integrated Index feature. If you do not select a specific database, by default all listed databases will be searched.
3. Click Search.
4. Search results identify all documents in the specified databases containing the search terms within the body text. Click the hypertext to access document outline and text.

Boolean and Proximity Operators

The following Boolean and Proximity Operators are available for use in the Boolean Search Boxes.

Example Search Tables

Boolean and Proximity Operators used in the Boolean Search Boxes can create a more precise search.

• You can add parentheses to nest expressions within a query. The expressions in parentheses are evaluated before the rest of the query. For example, entering "(personal OR protective) AND gloves" first searches for pages containing "personal" or "protective" (or both), then performs the AND search for pages containing "gloves." The results would return pages containing both "personal" and "gloves," and also pages containing both "protective" and "gloves." If you did not use the parentheses in this sample query, the AND expression "protective AND gloves" would be evaluated before the OR expression. Without the parentheses, the pages found would consist of those containing both "protective" and "gloves" (including those containing "personal") and also those containing "personal," though not containing "protective" or "gloves." Please note: Parentheses should only be used on the Advanced Search page.
  
  
• Use double quotes (“) to indicate that a Boolean or NEAR operator keyword should be ignored in your query. For example, “Abbott and Costello” will match pages with that phrase, not pages that match the Boolean expression. In addition to being an operator, the word and is a noise word in English.
  
  
• The NEAR operator is similar to the AND operator in that NEAR returns a match if both words being searched for are in the same page. However, the NEAR operator differs from AND because the rank assigned by NEAR depends on the proximity of words. That is, the rank of a page with the searched-for words closer together is greater than or equal to the rank of a page where the words are farther apart. If the searched-for words are more than 50 words apart, they are not considered near enough, and the page is assigned a rank of zero.
  
  
• The AND operator has a higher precedence than OR. For example, the first three queries are equal, but the fourth is not:

a AND b OR c
c OR a AND b
c OR (a AND b)
(c OR a) AND b

Wildcard operators help you find pages containing words similar to a given word.

Using the Document Comparison Feature

The Document Comparison feature allows an Integrated Index search to be initiated at any time without returning to the initial screen, and enables two documents to be viewed side-by-side for easy comparison.

How to use the Document Comparison feature:

1. Once you are in a document, click the Document Comparison button (located in the upper right-hand corner on the toolbar)
2. Select the type of search desired from the Search Type drop-down list.
3. In the Search Text box, enter the search term by a) highlight the term, then drag and drop it into the Search Text box (this option is only available with Internet Explorer 4.0), b) highlight the term, then copy and paste it into the Search Text box, or c) simply type in the new term.
4. Press the Search button.
5. On the left side of the screen, the current document appears. On the right side of the screen, search results for the new term entered using the Document Comparison feature appear.
6. Continue clicking the hypertext until you reach the desired document.

You have the option of closing either window at any time by clicking the button.

You may scroll through a document using the scroll bar on the right side of the document screen, or by pressing the Page Up and Page Down keys. Additional navigation is possible through the buttons at the top of and throughout a document:

	Takes you to the previous document section
	Takes you to a document outline; within the RegsLink System, takes you back to the table of contents for the Federal Register, the Code of Federal Regulations, or a specific state
	Takes you to the next available document section
	View or print the entire document, rather than just the open section
	Takes you back to the last search screen, allowing a new search of the same type (i.e., Integrated Index, Free-Text, etc.) to be initiated

Once you have a document open in the viewing window, you can copy text to the Windows Clipboard for use in other Windows programs:

1. Highlight the desired text by placing the mouse pointer at the beginning of the text, pressing and holding the mouse button, dragging it to the end of the text, then releasing it. The selected text is shown in reverse video.
2. Select Edit from the menu bar, then select Copy.

The ChemKnowledge® System allows you to print all of a page or only selected text (if available with your browser)

1. From within the desired page, click the toolbar button, or select Print from the File menu.
2. Select whether you wish to print the entire HTML page or document or a range of printed "pages" within the HTML page.
3. Click OK to begin printing.

From the Print dialog box, you can also set the print quality, number of copies (collated, if desired and available on your printer), and more.

1. Select the text you wish to print by placing the mouse pointer at the beginning of the text.
2. Press and hold the mouse button while dragging the pointer to the end of the text.
3. Release the mouse button, and the text appears in reverse video and is "selected."
4. Select the Print toolbar button or menu item to open the Print dialog box.
5. To print the selected text, choose Selection, then press Enter or click OK. Please Note: Selection will be dimmed and unavailable when no document text is selected.

The document assembly button appears within an open document and allows you to view or print the entire document, rather than just the open section.

To save an individual document for future use:

1. Open the document and select Save As File from the File menu.
2. Select the file name and directory to which you wish to save the file in the dialog box.
3. Select the format in which you wish to save the document (HTML or ASCII text).
4. Click OK.

Please Note: Table formatting will be lost when saving documents (this does not occur if using Word).
