Using the Query Operators
NOTE
The search engine interprets the search query based on a set of syntax rules. For
example, by entering the word region, the actual word region and all its stemmed
variations, such as regions and regional, are found. The search results are ranked for
importance, meaning how close the matched word comes to the originally input
search criteria. In the example above, region would rank higher than any of the
stemmed variants.
Not all queries rank their results. Only those queries that can have varying degrees
of matching can be ranked. For example, <CONTAINS queries either do or do not
contain the given string, but <NEAR queries can be ranked according to how close
the words are to each other. Words closer together are listed at the top of the search
results, while those that are far apart are put at the bottom of the results.

Default Assumptions
The search query language has some implicit defaults and assumptions that dictate
how your input is interpreted. In some cases, you can circumvent the defaults, but
the search engine decides what results to return using:
•
<STEM> Search finds all documents that contain any stemmed variant of the
search word or phrase. The search engine looks at the meaning of the word, not
just its spelling. For example, if you want to search plan, the results would
include documents that contain planning and plans, but not those that contain
plane or planet.
•
<MANY> Search considers how often the search word or phrase appear in the
found documents and ranks the results for frequency or relevancy.

The query language is not case-sensitive. The examples use uppercase for
clarity only.
