Function data_search_entries is not calculating correctly the totalcount

1. Create a course with a database using the image gallery preset
2. Enrol a couple of users as teacher and student in that course
3. As the student or teacher add at least 3 entries to the database
4. Enable "Mobile services": Site administration ► Mobile app ► Mobile settings
5. Create a Token in the mobile app service for the student in the course:
   • Click on Site administration ► Plugins ► Web services ► Manage tokens
6. Next, you can do a CURL REST call simulating a WS client with the student.
   • You need to replace the wstoken, databaseid (database instance id), the TEXTTOSEARCH with a text matching one of the images names and the URL of your moodle instance

     curl 'http://localhost/m/stable_master/webservice/rest/server.php?moodlewsrestformat=json' --data 'databaseid=8&wsfunction=mod_data_search_entries&wstoken=12a2a65aeea2a177055e233f9e303218&moodlewssettingfilter=true&search=TEXTTOSEARCH' | python -m "json.tool"

7. Now check that the totalcount match with the number of entries returned (if you found 1 entry, it should say 1)
8. If you execute the curl request removing the &search=X, totalcount should match the number of entries returned as well
9. If you search for a text that doesn't exit totalcount should be set to 0

Now, in the web interface check that the pagination when you do a Search in the View tab works as expected:

1. Create new entries in the database (minium a total of 5 entries required)
2. Set "Entries per page" to 2 and then do a search in the View tab. The search should match at least 3 entries.
3. Check that you see search 2 pages and you can navigate between the.
