Subject [jira] Resolved: (JCR-1045) jcr:contains does not return substrings with apostrophes
Date Mon, 13 Aug 2007 10:29:43 GMT

]

Marcel Reutegger resolved JCR-1045.
-----------------------------------

    Resolution: Invalid

If you are looking for an exact substring then you should rather use the jcr:like function:

//*[jcr:like(@title,'%Jackrabbit''s%')]

please also note that you do not necessarily have to escape the single quote in the string
literal.

The query:

//*[jcr:contains(@title,'*Jackrabbit\''s*')]

does not return results because the analyzer in jackrabbit does some basic stemming on the
text content. That is, the text "Jackrabbit's" is fulltext indexed as a single term "jackrabbit"
the 's is cut off. While this works fine with the first example you provided it does not when
you use wild cards in a jcr:contains function. In that case the query term is only lower-cased
but does not run through the analyzer. Hence, the 's is not cut off in that case and the term
will not match the indexed text.

> I am able to query for a node which has a property that contains the string "Jackrabbit's"
with the following:
>    //*[jcr:contains(@title,'Jackrabbit\''s')]";
> However, a substring search does not return any results:
>    //*[jcr:contains(@title,'*Jackrabbit\''s*')]
> Please advise.
