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.
