Search Tips Video
Searching by article number
Use the prefix WKB to search for an article number: WKB12345
Use modifiers to fine tune your query
|Use a preceding plus "+" to ensure that term must be included||unstable pressure +2695 will only show articles containing the term "2695"|
|Use a preceding minus "-" to only find articles not containing that term at all||unstable pressure -2695 will only show articles NOT containing the term "2695"|
|Use the boost operator "^" followed by a whole number between 2 and 10 to emphasize that term||unstable baseline Alliance 2998^5 will particularly prefer articles mentioning the 2998 while not completely excluding others|
|Use fields title , (product name) tag , or (article) content followed by a colon to specify particular sections of an article to be searched||
+title:usp uplc method development will only show results containing the term USP in the title
-title:"part number" 2489 lamp energy excludes part number articles
|Use double quotes to suppress similarity searching||+"ORA-00257" error in empower 3 will only show results about that specific ORA error|
|A wildcard "*" matches any number of characters, a question mark "?" represents a single character. Terms with wildcards in the middle should be enclosed in parentheses. It is not possible to have a wildcard at the beginning of a string.||
"Xevo TQ*" source maintenance will match all Xevo series tandem quads - the quotes ensure it doesn't match just TQD or ACQUITY TQD
One cannot match both 2777 and 3777 using wildcards, this can only be done as (2777 OR 3777) needle guide
|Use a range query [x TO y] to search for numeric ranges. The TO has to be all capitals.||+title:[228 TO 230] will find all articles containing numbers between 228 and 230 in the title. This can be useful when searching for background ions as it will find both nominal mass 229 and exact mass 229.1568|

Using the How can we help you? search field
As you have probably seen, you can enter search strings right in the "How can we help you?" field from the home page. In most cases, you will likely get the search result you are looking for.
Filtering search results from the How can we help you? search field
After getting your initial search results from this field, you can filter where your search occurs by clicking a category at the top of the search results field. The knowledge base automatically begins to search within that category.
Filtering with guides
After clicking a category, you can continue to filter results by clicking guides, which are child pages to categories. Again, the knowledge base automatically begins to search within that category.
