TIPS FOR EFFECTIVE SEARCHING:

Document Center's search engine can provide both quick and detailed search results. The default quick results will include only the latest revision of the documents returned. If detailed results are selected you can review a listing of past revisions as well.

Some tips to keep in mind:

Include dashes between parts of a document number in your search; "mil-std-883", or "IPC-A-600". This will focus your search on the exact document you are looking for. If you are unsure of the prefix leave it out altogether; "45208" brings up Mil-I-45208.
The search engine will evaluate both the document number and title fields in our database so a search on "ASQC-Z1.4" will bring up ASQC-Z1.4 as well as mil-std-105 which says "replaced by ASQC-Z1.4" in the title field.
When searching on IEC standard numbers try their 60,000 series number first such as IEC-61000-4-11. If this fails try their old numbering system which is 60,000 less: IEC-1000-4-11. IEC changed their numbering system in 1998 and some records in our database still reflect the old document numbers.
To view all standards from a particular source, search on the publishing agency's acronym followed by a wildcard: "IPC*" . This will return all standards from IPC up to the maximum number of hits and can be useful for viewing how their document numbers are formatted.
The following Boolean operators are supported by the Verity Search Engine used to search Document Center's standards database: and, "", *, ?, or, not, <near> (The near operator must be enclosed in angle brackets: <near> or the search engine will search for the actual word near). The near operator can limit distance between words by using a slash: "international <near/3> quality" will find all documents where the words international and quality are within 3 words of each other in the title.
The 'and' operator is used to combine your search words and will only return results where both words are present. For example a search on "electronic and assemblies" will omit results which do not contain both the words "electronic" and "assemblies" in the title. These words do not necessarily have to be adjacent.
When searching for a particular phrase use quotes around the phrase to return documents containing exact matches for that phrase. A search on "electronic assemblies" enclosed in quotes will return documents which have these words adjacent, but will omit any standards where both words are present, but in reverse order, or not next to each other.
The * operator is a wildcard . When placed at the end of a search query it will return all results with the root term no matter what the ending of the word may be. For example a search on "electro*" would return results containing the words electrode, electronic, electroplate and electromechanical.
? is useful for searching when you are unsure of the middle of a word or document number. A search for "ca?s" would return caps, cats, cars or cabs.
