Re: [dspace-tech] SOLR Configuration (Searching)

[Terry Brady]

Tom,

Thank you for the update.  I submitted a DSpace ticket to consider making
this change part of the default DSpace distribution.

 We found that the term stemming returned far too many false hits, so I
 changed several of our fields from "text" to "textgen" and the results were
 improved.

Re: [dspace-tech] SOLR Configuration (Searching)

[Tom Avino]

Terry,

I wanted to get back to you on this since you were so helpful with my SOLR 
search.
What I was doing wrong was, after I modified the schema.xml file, I 
ran dspace index-db-browse.  I was told by Tim Donahue, that I need to run 
index-discovery with the -b option.
So, everything is working great.  I am using your recommended textgen and 
am grateful for your help.

Thanks,

Tom Avino

Terry,

I was looking at the wrong schema.xml.  
I understand now.  This is from yours and it makes sense now.
Thank you again, and I will let you know if this works for me.  I think it 
will

Re: [dspace-tech] SOLR Configuration (Searching)

[Tom Avino]

Terry,

So I think I partially understand.  You modified the values in the 
"textgen" fieldtype in schema.xml.
But doesn't the line below define which type to use for a search?  Where do 
you specify to use "textgen" for a search?  I hope I am not giving you a 
headache.

Tom,

Here is my modified schema.xml for DSpace 5x:
https://gist.github.com/terrywbrady/097164329b2574b9d6bd4bb8433ca37b

I will be curious if this resolves issue for you.  If so, we might want to
propose this as an enhancement.

Terry,

Where and how did you change to textgen?  I guess that is what I cannot 
find,  I see it in schema.xml, but not sure where to change it.

Thanks

Re: [dspace-tech] SOLR Configuration (Searching)

[Terry Brady]

Unfortunately, I am not aware of any documentation on how to configure this
file for DSpace.

We found that the term stemming returned far too many false hits, so I
changed several of our fields from "text" to "textgen" and the results were
improved.

[dspace-tech] SOLR Configuration (Searching)

[Tom Avino]

Since we switched from Dspace 3.3 JSPUI to XMLUI, our search is not working 
the same. If our users type a specific item CA01234, it will not find this 
even though it is in one of the metadata fields.  I am not sure how SOLR 
works.  I have looked what is in schema.xml.  I am unclear which fieldtype 
is used when a search is done.  It looks like each fieldtype can have 
different parameters.  There is "text_ws", "text", "textTight", etc.
Where in Dspace do you pick which one to use during a search???

Example
