Problema with search-indexing

[Roberto Greiner]

Hi,

I'm having some trouble with searches inside of PDF files.

For some reason, the search only seems to work when the PDF is small
(less than 15MB or 100 pages).

I've uploaded some small files, and after running "dspace filter-media",
I get results for searches inside of files with these sizes:
1.4MB and 10 pages
11MB and 57 pages

I uploaded somewhat larger files:
17MB  and  101 pages
58MB   and 218 pages
15MB   and 137 pages

For these documents, the search does not find anything at all inside the
documents, even if I search for something in the first page.

Additionally, I've downloaded a large file from another DSpace from a
contact of mine. This file has 625MB and 188 pages. In his DSpace
(running dspace 7) the search works. In mine it does not.

When I run "dspace filter-media" I don't get any errors, and
thumbnails/miniatures are being generated for all documents.

Does anyone know what could be happening?

Thank you,

Roberto Greiner

Hi Roberto


By default, DSpace has a character limit of 100,000 for full-text indexing in the Discovery module. If you need to increase this limit, you can follow these steps:

Navigate to the following file in your DSpace installation:

      -[dspace] config/modules/discovery.cfg
      -Look for the property:
           #discovery.solr.fulltext.charLimit=100000

Uncomment this property (if it is commented) and update the value to your desired limit, e.g.,
discovery.solr.fulltext.charLimit=200000


After updating the character limit, you must reindex all the objects to apply the changes. Run the following command:

                [dspace]/bin/dspace index-discovery -f

Just as I thought: something simple needed to be changed. Now it's working perfectly.

Thanks!!!!
