Text.escapeIllegalXpathSearchChars doesn't work correct - Full text search
failed
---------------------------------------------------------------------------------
Key: JCR-2416
URL: https://issues.apache.org/jira/browse/JCR-2416
Project: Jackrabbit Content Repository
Issue Type: Bug
Components: jackrabbit-jcr-commons
Affects Versions: 1.6.0
Environment: Don't matter
Reporter: Oleg Varaksin
Priority: Minor
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(*, cssns: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.
