Detailed Search Tips
To perform a search, enter a few descriptive words, catalog number or product name. Search will return any documents or web pages containing any of the words from your query. You can refine or narrow your search by subtracting words from your query or using filtering within the top or left column.
Support Search by Category
Your search can be narrowed initially to specific categories using the dropdown between the text box and the Search button. By default, your previous search category is selected but you can alter your search category between: Manuals & Protocols, Product Literature, Citations & References, Media Formulations, COAs, LULLs, MSDS, Vector Maps, Chemical Structures, Spectra Data, Product FAQs, Ordering & Web FAQs.
Some search collections offer filtering on result data. These filters when available will be displayed in the left hand column. Some search categories have multiple filters depending on the content available.
Word Variations (Stemming)
To provide the most accurate results, search does not use "stemming" or support default "wildcard" searches. In other words, search looks for exactly the words that you enter in the search box. Searching for "lenti" will not yield "lentivirus" or "lentiviral".
Automatic "and" Queries
By default, search returns pages that include all of your search terms. Keep in mind that having more than one word on the page will tend to boost the relevancy and the rank of the result. To restrict a search further, just include more terms.
Search for complete phrases by enclosing them in quotation marks. Words enclosed in double quotes ("like this") will appear together in all results exactly as you have entered them.
Automatic Exclusion of Common Words
Search ignores common words and characters such as "an" and "the", as well as certain single digits and single letters, because they tend to slow down your search without improving the results.
A method for forcing search to include these "stopwords" is conducting a phrase search, which means putting quotation marks around two or more words. Common words in a phrase search (e.g., "where are you") are included in the search.
Searches are NOT case sensitive. All letters, regardless of how you type them, will be understood as lower case. For example, searches for "Gateway", "gateway", and "GATEWAY" will all return the same results.
