Subject [jira] Updated: (JCR-2416) Text.escapeIllegalXpathSearchChars doesn't work correct - Full text search failed
Date Tue, 01 Dec 2009 11:57:20 GMT

     [ https://issues.apache.org/jira/browse/JCR-2416?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Oleg Varaksin updated JCR-2416:
-------------------------------

    Description: 
Hello,

I use instructions from http://wiki.apache.org/jackrabbit/EncodingAndEscaping to escape values
in queries for full text search, but the method Text.escapeIllegalXpathSearchChars does something
strange replacements. If I want to search a whole phrase I surround the text with double quotes.
This is described in JCR 170 (section 6.6.5.2 jcr:contains Function) A term may be either
a single word or a phrase delimited by double quotes ("). Well. I write now a String "\"Have
much fun\"", pass it through Text.escapeIllegalXpathSearchChars and let execute then query.
An exception is thrown:

javax.jcr.RepositoryException: Exception building query: org.apache.lucene.queryParser.ParseException:
Cannot parse '"Have much fun\"': Lexical error at line 1, column 17.  Encountered: <EOF>
after : "\"Have much fun\\\""

I think, Text.escapeIllegalXpathSearchChars doesn't work correct if the whole phrase is surrounded
by \" (double quotes within String) and the sign \" is the last sign.

Query statement: //element(*, nt:file)[jcr:contains(jcr:content, '""Have much fun"')]
Executing: QueryManager.createQuery(statement, Query.XPATH).execute();

I use as dependency Apache Lucene Core 2.4.1. As workaround I call now simple userValue.replaceAll("'",
"''"); instead of Text.escapeIllegalXpathSearchChars(userValue).replaceAll("'", "''") and
it works fine!

Best regards.
Oleg.
