While parsing,
During debugging, control goes to the below method of QueryBuilder.java class
*protected final Query createFieldQuery*(Analyzer analyzer, BooleanClause.Occur
operator, String field, String queryText, boolean quoted, int phraseSlop) {}
Where arguments are:
*analyzer:* Analyzer analyzer = new WhitespaceAnalyzer(Version.LUCENE_47);
*field:* "P_id"
*queryText:*
"/content/usergenerated/asi/cloud/content/sites/collaboration-for-development/en/groups/eastern-partnership-transport-panel/groups/eastern-partnership-transport-panel-road-safety/forum/jcr:content/content/primary/forum/test_my_asrp-1KN5/l2-kQnn/l3-kiVI/l4-wZeN/checking_again-tUzu"
*quoted*: true
*phraseSlop:* 0
Inside this method query divided into 2 termAttr.

String got cut after 255 lengths. Later both terms added to PhraseQuery object
Code snippet from lucene code

int positionIncrement = 1;
try {
boolean hasNext = buffer.incrementToken();
assert hasNext == true;
termAtt.fillBytesRef();
if (posIncrAtt != null) {
positionIncrement = posIncrAtt.getPositionIncrement();
}
} catch (IOException e) {
// safe to ignore, because we know the number of tokens
}
if (enablePositionIncrements) {
position += positionIncrement;
pq.add(new Term(field, BytesRef.deepCopyOf(bytes)),position);
} else {
pq.add(new Term(field, BytesRef.deepCopyOf(bytes)));
}

> Project: Lucene - Core
> Issue Type: Bug
> Reporter: Akanksha Jain
> Priority: Major
>
> Hello Everyone
>
> I am working with Lucene 4.7.1
> When parsing query using Lucene query parser. If query length is greater than
> 255 bytes, it returns query with space appended after every 255 bytes, which
> is causing further issues in my project.
>
> Can you please let me know why the term (parsed query contain
> Arraylist<Term>) max length is 255 bytes. Why space is appended in between
> the query?
>
> I will really appreciate it if someone can help me with this.
> Do let me know if you have not understood my query and require some reference
>
> For analysis, Please check QueryBuilder.java class which has method
> createFieldQuery(....)
