solr chunking

[Richard Shrake]

Can someone point me to a good resource on how to configure the way solr recognizes terms for facets? I've got facets like "and" showing up, which looks kind of silly.

Thanks!

[David Wilcox]

Hi Richard,

There's a great, freely available guide to Solr here:
http://www.lucidimagination.com/devzone/references/solr-guide. The
latest version of the guide has a section on facets here:
http://lucidworks.lucidimagination.com/display/solr/Faceting.

Does this give you the information you need? Or do you need more
Islandora-specific information?

Regards,

David

Thanks, David. I'll take a look.

If you see 'and' then it's an indication your faceting is being done on tokenized types. You can start your investigation by using 'string' type rather than 'text' type field values.

Thanks. In the Islandora Solr Client config settings, I changed the Facet Fields from dc.subject to dc.subject_s, but when I do that, I don't get any facet results. Is there another step to include the string values?

Gravedigging this, I'm not clear myself on what I need to change to make sure I'm using strings and not text. I also get nothing when I add _s

I was under the impression the solution pack shipped with DC/MODS fields configured?

[Richard Shrake]

If you go to http://[yourserver]:8080/solr/admin/schema.jsp and examine some of the fields, are you showing results?

Yes, I see:

Field: dc.subject

Dynamically Created From Pattern: *

Field Type: TEXT_FGS

Schema: Indexed, Tokenized, Stored, Multivalued

Index: Indexed, Tokenized, Stored

Index Analyzer: org.apache.solr.analysis.TokenizerChain DETAILS

Query Analyzer: org.apache.solr.analysis.TokenizerChain DETAILS

Docs: 27

Distinct: 164

But under Field Types I see this bit:

Field Type: string

Fields: PID MANU_EXACT *_S

Tokenized: false

Class Name: org.apache.solr.schema.StrField

Index Analyzer: org.apache.solr.schema.FieldType$DefaultAnalyzer

Query Analyzer: org.apache.solr.schema.FieldType$DefaultAnalyzer

[Aaron Collie]

I'm not seeing much in my schema.xml  (attached)... did I not configure properly?

[Richard Shrake]

Yes, it looks like you missed something somewhere. You might want to re-run through the steps of installing SOLR and gsearch - I know I had to do it again because I flubbed a step somewhere. Sorry I don't remember all of the details.

The solr_schema.xml file does all the out-of-the-box copying of dc and mods metadata to strings.

[Aaron Collie]

I just walked through this again:

https://wiki.duraspace.org/pages/viewpage.action?pageId=31659944

But I'm still ending up with the same schema.xml; I wonder what I'm missing (twice).

[Aaron Collie]

Update for anyone who finds this thread a couple months later (like I did). I borrowed the sandbox schema.xml, dropped it in place, and things seem to be working.
