||Select one category or all categories.
|Word or phrase
||Search on a word such as "adverse" or a phrase such as "adverse event".
|Beginning of word
||Search on the beginning of a word. For example, searching on "investigat" finds "investigator" and "investigational", but not "subinvestigator".
||Search on text that may occur in the middle of a word or across words. For example, searching on "investigator" finds "subinvestigators"; searching on “to cha” finds “to chance”.
|Punctuation is significant
||Limit results based on the presence or absence of punctuation. For example, searching on "FDA-approved" finds only "FDA-approved", while searching on "FDA approved" finds only "FDA approved". With this option unselected, searching on "crossover" will find both "crossover" and "cross-over".
|Search within results below
||If your initial search returns too many results, this option allows you to search only among the results previously found.
- If the text in the search box looks like a citation, such as "45 CFR 164.512" or "21 CFR 17.45(b)(3)", the response is to show the regulation (such as 45 CFR 164 or 21 CFR 17) with the cited passage highlighted.
- You can use spaces instead of the other punctuation: "21 cfr 17 45 b 3".
- Currently, only CFR citations are recognized.
- Indenting has been added to make the text more readable.
- Subsection numbers in the original documents that obviously appear to be missing have been added.
- Searches only find instances where the exact text in the search box is found. For example, searching for “event adverse” finds no results.
- Results are displayed based on the number of times the search term is found in the document.
- Surrounding a search phrase with quotation marks has no effect, unless you select "Punctuation is significant".
- Words such as “and” and “or” are interpreted as part of the search phrase.
- Red underlining indicates where the search term has been found in the title. Searches in the body of the article are not shown.
- Search terms that are singular and present-case with U.S. English spelling are more likely to find results.
- Use the arrows on the left to view other pages in a document. Use the arrows on the right to skip to the next page where the search term is found.
