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.
Filtering
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.
Phrase Searches
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.
Capitalization
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.
