Hello everyone,
I'm recently seeing this error a lot:
** Traceback details

IndexError: string index out of range
I've noted that the problem arises only when all the following are true:
- Externally hosted collections
- The &f in the search uri has a value (ie &f=title, &f=year, etc). The
same searches in the 'any field' index work without errors.
- The search-for value must be empty
- Search is performed from within the external collection (see below for
explanation)
Steps to replicate:
1. Go inside an externally hosted collection (do NOT just click search
in the top collection and then select the external collection from the
dropdown menu, as the error does NOT(!) appear).
2. Select a search index other than 'any field'
3. Leave the search-for term, empty
4. Hit search
Can you verify my findings? If so, I should probably create a ticket...
Best regards,
Theodoros Theodoropoulos
ps. btw, I don't think it's a timeout issue because the same search in
the other invenio server that hosts the collection returns results
almost instantly.
