DGB commented on LUCY-299:
--------------------------
Hi Nick,
I'm not setup for a "minimal test case" at this moment, would need a little
more time to try that (which I'd be happy to do).
Meanwhile, just looking at the text of your script, here are potential deltas I
can see:
* I'm not setting the "truncate" flag in Indexer-new (I was however running the
tests after doing "rm -rf" on the folders containing the indexes).
* The two entries I'm adding are a bit different, for <content, title> they're:
"/Building.txt", "Building.txt"
"/java txt", "java txt"
* I am committing the index after each add-doc (i.e. twice)
* For the search, I am not doing a term-query to search against a specific
field (I believe you are searching against the title field), but rather doing
IxSearcher-New on the index folder then IxSearcher-Hits to get the results
(mirrors code in getting_started.c). Do I understand correctly that I am
therefore searching all searchable fields?
* Also worth noting that the actual field I'm getting the matches for (in the
case I don't use blob for content) is title I believe.
* I am using C rather than Perl, though hopefully that doesn't matter...
If you have a chance to try a modified version of your test script that would
be great; otherwise I will try and replicate myself using a variant of your
script once I'm able.
Thanks for taking a look.

> Key: LUCY-299
> URL: https://issues.apache.org/jira/browse/LUCY-299
> Project: Lucy
> Issue Type: Bug
> Components: Core
> Affects Versions: 0.4.4
> Environment: Ubuntu 15.10
> Reporter: DGB
> Labels: github-import, newbie
>
> Running into an apparent issue using BlobType_new to create FieldType.
> Scenario:
> Creating a schema with two fields, "fullpath" and "title". Using EasyAnalyzer.
> Add a couple of entries to the index
> Issued a search against the index
> Problem: If for fullpath field I use BlobType_new for FieldType, no search
> match is found. However, if I use either FullTextType_new or StringType_new
> for the schema FieldType of fullpath, it works fine.
> If I do not add fullpath at all, not to schema nor of course with Doc_Store -
> i.e. just have a single field of title - my scenario works fine (get a search
> hit).
> If I add fullpath to the schema, but not to the doc entries (via Doc_Store),
> it works fine (get a search hit).
> It makes no difference (still get no match) if add fullpath before or after
> title.
> It makes no difference (still get no match) whether I pass true or false as
> parm to BlobType_new.
> In all cases, FieldType for title is fulltext; and it is title that is
> generating the matches against the search query.
