Bug in QueryParser ?
I´ve got the following Exeption during my tests with a query like word1 || word2 || word3 if one of the words, e.g. word2 is in the stopword - list of my Analyzer : java.lang.ArrayIndexOutOfBoundsException: -1 < 0 at java.util.Vector.elementAt(Vector.java:427) at org.apache.lucene.queryParser.QueryParser.addClause(QueryParser.java:171) at org.apache.lucene.queryParser.QueryParser.Query(QueryParser.java:463) at org.apache.lucene.queryParser.QueryParser.parse(QueryParser.java:113) I´m using Lucene 1.3 rc1. Is this a Bug ? Michael - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
How to search for ':'
Hey, is there a way to search for phrases including the ':' character, e.g. in file pathes. Thanks -- +++ GMX - Mail, Messaging & more http://www.gmx.net +++ Bitte lächeln!

How to get field contents
Hello, I'd like to build a list with all values from a certain field that occur in an index. Looking at the API, there's a method getFieldNames(), but I already know the field name, I want to get a list of all the values. Also, I can enumerate fields by giving Terms, but a Term means I have to have the field name and value. Can this be done?

Limited range in RangeQuery
It seems that Lucene can't handle RangeQueries with a range of something over 1024. Is this a limitation or a bug (or am I doing something wrong)? +length:[null TO 01026] -> OK +length:[null TO 01027] -> BooleanQuery$TooManyClauses +mass:[001 TO 0011026] -> OK +mass:[001 TO 0011027] -> BooleanQuery$TooManyClauses -- Eric Jain - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Yes, this is a known bug. It's in Bugzilla.

Re: How to search for ':'
Yes, using \ as the escape character, and an Analyzer that doesn't discard \. Look at TestQueryParser.java for examples.

Re: Limited range in RangeQuery

Solved: BooleanQuery.setMaxClauseCount(Integer.MAX_VALUE); It seems Lucene needs to expand [1000 - 2000] into '1000 or 1001 or 1003 or ...' (assuming 1002 does not occur in the index).

RE: How to get field contents
As far as I know you will have to go throught the index and verify the
field field (that is not an error) of each term:
IndexReader reader = IndexReader.open("index");
TermEnumte = reader.terms();
while ( te.next() ) {
Term tt = te.term();
String fieldOfTerm = tt.field();
if ( fieldOfTerm.compareTo( "contents" ) ) {
do_something_silly()...
} else if ( fieldOfTerm.compareTo( "path" ) ) {
do_something_silly2()...
}
}

Re: How to get field contents
This can be done more efficiently if you only want to enumerate the
terms of a particular field. Term enumerations are ordered first by
field, then by the term text. You can also specify the initial position
of a term enumeration. Thus an efficient enumeration of the terms in
"myField" can be done with something like:
IndexReader reader = IndexReader.open("index");
TermEnum te = reader.terms(new Term("myField", ""));
while (te.term() != null && "myField".equals(te.term().field())) {
... do something silly ...
te.next();
}

Strange problem while indexing?
i am using lucene to index xml+html files. the xml contains the metadata associated with the html file. the process, at a high level, is: -create a list of all xml files in a folder -parse through each of the xml file using SAX parser -create name:value pairs out of the tags and values, and index them -one of the tag contains the url to the html page -when you encounter that, parse the html file when i do this for a few files, it seems to work fine. however, as the number of files increase, it starts to throw an error! initially, i get a "SAXException: Content is not allowed in trailing section." - but i checked and the xml file seems to be well-formed! i even tried indexing this file individually, and it worked! then i get "Index locked for write: Lock@/export/home.../write.lock" at times, i also get a "Timed out waiting for: Lock@/export/home/.../commit.lock" as a result of this, the index doesnt get updates and the results are incorrect. i also observed once that while the index is being built, i get the results, but when it exits, i stop getting results. possibly, my hunch is that index updation didnot get commited? what is particularly intersting to note is that this problem occurs at only some times. another observation is that it worked fine for around 50 files, but not for about 100 files? can anyone help me - or give pointers as to what is going on here? -rishabh Get advanced SPAM filtering on Webmail or POP Mail ...
