Querying language
From OpenSearchServer Wiki
At this stage of the development roadmap, OSS uses the basic Lucene querying syntax.
This syntax is fully documented at http://lucene.apache.org/java/2_4_1/queryparsersyntax.html .
Sample query:
title:($$)^10 OR title:("$$")^10
OR
titleExact:($$)^10 OR titleExact:("$$")^10
OR url:($$)^5 OR
url:("$$")^5
OR urlSplit:($$)^5 OR urlSplit:("$$")^5
OR
urlExact:($$)^5
OR urlExact:("$$")^5
OR content:($$) OR
content:("$$")
OR
contentExact:($$) OR contentExact:("$$")
