Searches in the test servers that work under postgresql and without Elasticsearch should now work correctly.
Please refer to the original report
to see a complete description of the performed tests that should now be working. I'll write down one possible test for reference:
1.- Log into postgres.test server
2.- Post the following message: This is a private channel message you will see again later.
3.- Search for "private channel message" without quotes.
Expected: The message posted on step 2 should appear as a search result.
