Hello,
I have a QParser impl. that transforms text input to one or more integers, it
makes a BooleanQuery one a field with all integers in OR-more. It used to work
by transforming the integer using LegacyNumericUtils.intToPrefixCoded, getting
a BytesRef.
I have now moved it to use IntPoint.newRangeQuery(field, integer, integer), i
read (think javadocs) this is the way to go, but i get no matches!
Iterator<Integer> i = digests.iterator();
while (i.hasNext()) {
Integer digest = i.next();
queryBuilder.add(IntPoint.newRangeQuery(field, digest, digest),
Occur.SHOULD);
}
return queryBuilder.build();
To be sure i didn't mess up elsewhere i also tried building a string for
LuceneQParser and cheat:
Iterator<Integer> i = digests.iterator();
while (i.hasNext()) {
Integer digest = i.next();
str.append(ClientUtils.escapeQueryChars(digest.toString()));
if (i.hasNext()) {
str.append(" OR ");
}
}
QParser luceneQParser = new LuceneQParser(str.append(")").toString(),
localParams, params, req);
return luceneQParser.parse();
Well, this works! This is their respective debug output:
Using the IntPoint range query:
<result name="response" numFound="0" start="0">
</result>
<lst name="debug">
<str name="rawquerystring">{!q f=d1}value</str>
<str name="querystring">{!q f=d1}value</str>
<str name="parsedquery">(d1:[-1820898630 TO -1820898630])</str>
<str name="parsedquery_toString">d1:[-1820898630 TO -1820898630]</str>
LuceneQParser cheat, it does find!
<result name="response" numFound="2" start="0">
<doc>
<str name="id">1</str>
<int name="d1">-1820898630</int></doc>
</result>
<lst name="debug">
<str name="rawquerystring">{!qd f=d1}value</str>
<str name="querystring">{!qd f=d1}value</str>
<str name="parsedquery">d1:-1820898630</str>
There is not much difference in output, it looks fine, using LuceneQParser you
can also match using a range query, so what am i doing wrong?
Many thanks!
