Hi James,
The request
/spellcheck?spellcheck=true&spellcheck.q=quiam&spellcheck.dictionary=fuzzy2
returns
quidam, quam, quia, quoniam, quidem, quadam, quodam, quoad, quedam,
quis, quae, quas, quem, quid, quin, qui, qua
Replacing quiam (not in the index) by quidam (in the index) returns
nothing at all, but I want it to return
quidam, quam, quia, quidem, quadam, quodam, quedam, ...
When I was using the same parameters with IndexBasedSpellChecker, by
setting a high alternativeTermCount, I got results for both. But as I
said, then I can't differentiate the different maxEdits.
The request handler is:
<requestHandler name="/spellcheck"
class="org.apache.solr.handler.component.SearchHandler">
<lst name="defaults">
<str name="spellcheck.dictionary">fuzzy1</str>
<str name="spellcheck.count">20</str>
<int name="spellcheck.alternativeTermCount">1000000</int>
</lst>
<arr name="last-components">
<str>fuzzyterms</str>
</arr>
</requestHandler>
Thanks!

Nathaniel,
Can you show us all of the parameters you are sending to the
spellchecker? When you specify "alternativeTermCount" with
"spellcheck.q=quidam", what are the terms you expect to get back?
Also, are you getting any query results back? If you are using a "q"
that returns results, or more results than you specify for
"spellcheck.maxResultsForSuggest", spellcheck won't give you anything
regardless of what you put for "spellcheck.q".

Subject: fuzzy terms, DirectSolrSpellChecker and alternativeTermCount
Hello,
I'm trying find the best way to "fake" the terms component for fuzzy
queries. That is, I need the full set of index terms for each of the
two queries "quidam~1" and "quidam~2".
I tried defining two suggesters with FuzzyLookupFactory, with
maxEdits=1 and 2 respectively, but the results for "quidam~1" include
suffixes like "quodammodo", which makes sense for a suggester but
isn't
what I want here.
Now I'm trying with the spell-checker. As far as I can see,
IndexBasedSpellChecker doesn't let me set maxEdits, so I can't use it
to distinguish between my two queries. DirectSolrSpellChecker seems
like it should work, ie:
<searchComponent name="fuzzyterms" class="solr.SpellCheckComponent">
<lst name="spellchecker">
<str name="name">fuzzy1</str>
<str name="classname">solr.DirectSolrSpellChecker</str>
<int name="maxEdits">1</int>
...
</lst>
<lst name="spellchecker">
<str name="name">fuzzy2</str>
<str name="classname">solr.DirectSolrSpellChecker</str>
<int name="maxEdits">2</int>
...
</lst>
</searchComponent>
However the parameter spellcheck.alternativeTermCount has no effect,
so
the query "spellcheck.q=quidam" gives no results, but
"spellcheck.q=quiam" (which doesn't exist in the index) gives the
expected terms.
Am I missing something? Or is there a better way to do this?
Many thanks for any help and ideas,
Nathaniel
