Now that I am reading the specifications I see following for jcr:contains()
function :
--- begin quote ---
At minimum, all implementations must support the simple search-engine syntax
defined by exp in the EBNF above. This syntax is based on the syntax of search
engines like Google.
The semantics of the simple search expression are as follows:
• Terms separated by whitespace are implicitly ANDed together.
• Terms may also be ORed with explicit use of the OR keyword.
• AND has higher precedence than OR.
• Terms may be excluded by prefixing with a – (minus sign) character. This
means that the result set must not contain the excluded term.
• A term may be either a single word or a phrase delimited by double quotes (").
• The entire text search expression (searchexp in the EBNF, above) must be
delimited by single quotes (').
• Within the searchexp literal instances of single quote (“'”), double quote
(“"”) and hyphen (“-”) must be escaped with a backslash (“\”). Backslash itself
must therefore also be escaped, ending up as double backslash (“\\”).
--- end quote ---
Does this mean if I have a form in which user is entering search query I don't
have to "build" (tokenize, validate, reconstruct, etc, etc) the XPAth query...
I can just pass in something like
jcr:contains(.,'rock AND roll OR disco -techno') and it will work?
Would I have to take care of the last point (escape special chars) or is that
done automatically?
Thanks
