Elizabeth Haubert commented on SOLR-12243:
------------------------------------------
I think the problem is EdismaxQParser:: ln 1393. super.getFieldQuery returns a
SpanNearQuery, which is not an instanceof type BooleanQuery or PhraseQuery or
MultiPhraseQuery. So the query parser decides it didn't get a legit phrase
query back, and throws it out.
What is the history around what query types are allowed as a phrase query and
which aren't?
private Query getQuery() {
try {
switch (type) {
case FIELD: // fallthrough
case PHRASE:
Query query;
if (val == null) {
query = super.getFieldQuery(field, vals, false);
} else {
query = super.getFieldQuery(field, val, type == QType.PHRASE, false);
}
// Boolean query on a whitespace-separated string
// If these were synonyms we would have a SynonymQuery
if (query instanceof BooleanQuery) {
BooleanQuery bq = (BooleanQuery) query;
query = SolrPluginUtils.setMinShouldMatch(bq, minShouldMatch, false);
}
if (query instanceof PhraseQuery) {
PhraseQuery pq = (PhraseQuery)query;
if (minClauseSize > 1 && pq.getTerms().length < minClauseSize) return null;
PhraseQuery.Builder builder = new PhraseQuery.Builder();
Term[] terms = pq.getTerms();
int[] positions = pq.getPositions();
for (int i = 0; i < terms.length; ++i) {
builder.add(terms[i], positions[i]);
}
builder.setSlop(slop);
query = builder.build();
} else if (query instanceof MultiPhraseQuery) {
MultiPhraseQuery mpq = (MultiPhraseQuery)query;
if (minClauseSize > 1 && mpq.getTermArrays().length < minClauseSize) return
null;
if (slop != mpq.getSlop()) {
query = new MultiPhraseQuery.Builder(mpq).setSlop(slop).build();
}
*} else if (minClauseSize > 1) {*
*// if it's not a type of phrase query, it doesn't meet the minClauseSize
requirements*
*return null;*
*}*
