Tom Burton-West commented on SOLR-744:
--------------------------------------
I applied both this and LUCENE-1370 and there seems to be some problem with
passing arguments from the ShingleFilterFactory to the ShingleFilter. The
admin analyzer says that outputUnigramIfNoNgram=true
org.apache.solr.analysis.ShingleFilterFactory {outputUnigrams=false,
outputUnigramIfNoNgram=true}
However, this does not seem to be getting set within the ShingleFilter and the
admin analyzer shows nothing coming out of the ShingleFilterFactory when
analyzing a query with a single word.
when using the admin interface to query a single word, I also get no results.
If I hack the patch by always setting outputUnigramsIfNoNgrams to true,
everything works fine.
(see below)
If I am missing something or obviously doing something wrong, please let me
know. In the meantime I will try to write a unit test and track down the
problem. Is there an already existing unit test I could use as a model?

public void init(Map<String, String> args) {
super.init(args);
maxShingleSize = getInt("maxShingleSize",
ShingleFilter.DEFAULT_MAX_SHINGLE_SIZE);
outputUnigrams = getBoolean("outputUnigrams", true);
outputUnigramIfNoNgrams = true;
/** tbw lets always set it to true above
* comment out the original code below
getBoolean("outputUnigramIfNoNgram", false);
**/
