Search Query with editdistance - throws Null Pointer
When I run the following query (Solr 4.10.2) with edit-distance, I'm
getting a null pointer exception:
*<host>/solr/select?q=fld:(Event
ID)&fl=strdist("eventid",fld_alphaonly,edit)*
<response><lst name="error"><str name="trace">java.lang.NullPointerException
</str><int name="code">500</int></lst></response>
It works if I remove the space between "Event ID", like:
*<host>/solr/select?q=fld:(EventID)&fl=strdist("eventid",fld_alphaonly,edit)*
Here is the schema details:
<field name="fld" type="text" indexed="true" stored="true"/>
<field name="fld_alphaonly" type="alphaonly" indexed="true" stored="true"/>
<copyField source="fld" dest="fld_alphaonly" />
<fieldType name="alphaonly" class="solr.TextField" sortMissingFirst="true"
omitNorms="true"> <analyzer> <charFilter class=
"solr.HTMLStripCharFilterFactory"/> <filter class=
"solr.LowerCaseFilterFactory"/> <filter class=
"solr.PatternReplaceFilterFactory" pattern="([^a-z])" replacement="" replace
="all"/> <tokenizer class="solr.KeywordTokenizerFactory"/> </analyzer> </
fieldType> <fieldType name="text" class="solr.TextField"
positionIncrementGap="100"> <analyzer> <tokenizer class=
"solr.StandardTokenizerFactory"/> <filter class="solr.StandardFilterFactory"
/> <filter class="solr.TrimFilterFactory"/> <filter class=
"solr.ICUFoldingFilterFactory"/> </analyzer> </fieldType>
Any suggestions would be appreciated.
Thanks

Thanks Hoss.
But how do we avoid this error?
Is there anyway to tweak the query and return empty result instead of null
pointer exception?

What's the full stack trace in your server logs?
