Match any single search word
You may search for pages which contain AT LEAST ONE of the given search terms.
Match multiple search words (Boolean OR logic)
OR logic collates your search results to retrieve all unique records containing one term, the other term, or both of them. For example, your search for “micro-insert OR device” would retrieve all unique records containing the term “micro-insert,” the term “device,” or both of these terms.
Adding more terms to a OR search will retrieve more results.
The results will be sorted in order of the number of terms matched, and the determined relevancy score (see Notes on Results Relevance below for more details).
Wildcard searches
Wildcard characters “*” and “?” can be used in search terms for multiple words and return larger set of results. An asterisk character ('*') in a search term represents any number of characters, while a question mark ('?') represents any single character.
This allows you to perform advanced searches such as "con*" which would return all pages containing words beginning with "con". Similarly, "m??e " would return all pages containing four letter words beginning with 'm' and ending with 'e' like “make” and “mate”. Also, "*con*" would be a search for any words containing the word "con" like control, concomitant, etc.
Exact phrase Search
An exact phrase search returns results where the phrases of words are found in the same order that they are specified. For example, an exact phrase search for the words "permanent birth" would only return results where the phrase 'permanent birth' appears. It would not return pages where the words 'permanent' and ‘birth' are found separately, or in a different order such as, 'birth permanent'.
To specify an exact phrase search term, you need to enclose the words that form the phrase using double quotation marks. You can also combine the use of exact phrase searches with normal search terms and wildcard search terms within a single search query (eg. "permanent birth" control*). Note however, that wildcards within exact phrases (eg. "permanent birt*") are not supported.
Exclusion/negative searches
You can precede a search term with a hyphen character to exclude that search term from being included in your search results. For example, a search for "permanent -control" would return all pages containing the word "permanent" but not the word "control".
Skip words
Common words like “the”, “and”, and “or” (or words entered into the Skip Words list) will be ignored from the search.
Capitalization
Search is not case sensitive. Capital letters are treated as though they were lower case and do not affect the search.
Notes on Results Relevance
Several factors affect the relevance of the results, including: 1. The number of times the searched term appears on that page. 2. The number of search terms that appears on the page. 3. The individual words that form part of an 'exact phrase' query. 4. The density of the words on the page. 5. The page depth (If the page is a deep page or top level page) 6. Whether the word appears in the title, meta description, meta keywords, or header tags part of the page or in the file name.
