[OPS] Full text search not working


In an instance of OPS 3.2.1 the full-text search is not working.

In config.inc.php we add the line below:

index[application/pdf] = "/usr/bin/pdftotext -enc UTF-8 -nopgbrk %s - | /usr/bin/tr '[:cntrl:]' ' '"

And then we run the

php rebuildSearchIndex.php

Even after weeks, nothing has changed. We didn’t find PDF terms, just the same results as the standard OPS indexing.

We downloaded a PDF on the server and tested it via the command line for testing and the output was the full text, as expected:

/usr/bin/pdftotext -enc UTF-8 -nopgbrk "1397-Preprint Text-2293-3-10-20201023.pdf" - | /usr/bin/tr '[:cntrl:]' ' '

[PDF fulltext output here]

Could you guide us on how to find out why it is not working?

note: I created a new topic, because the ones I found are for OJS.


Did you see any errors during the rebuild?

@ajnyga, the technician responsible for this installation, perform the rebuild again and the indexing seems to have happened as expected now.

I appreciate the attention.
