Steps to reproduce:

1. Add a web content article titled "stable" (include the quote characters in the title)
2. Add a web content article titled upstream
3. Add a web content article titled git hash
4. In the home page embedded search bar, search for "stable" (quotes included)

   Observed behavior: The "stable" web content article appears in the search results

5. In the Control Panel > Configuration > Search Tuning portlet, add the following synonym set: "stable", upstream
6. Back on the home page, search for "stable"

   Observed behavior: The "stable" and upstream web content articles appear in the search results

7. Edit the synonym set added earlier and add the synonym git hash
8. Back on the home page, search for "stable"

   Expected Result: The web content articles "stable", upstream, and git hash appear in the search results
   Actual Result: Only git hash appears in the search results

9. Edit the same synonym set, delete synonym git hash, and add the synonym git has
10. Back on the home page, search for "stable"

    Expected Result: The web content articles "stable", upstream, and git hash appear in the search results
    Actual Result: No search results appear

11. Search for git has

    Observed behavior: The web content article "stable", upstream, and git hash appear in the search results

Note: I couldn't find a consistent pattern of behavior that would lead to the odd search results. I believe it has something to do with the combination of both the quoted synonym and a synonym that has a space in it. Using characters like a dash "-" or semicolon ";" instead of a space seems to result in the same behavior.
