Inconsistency in Code search

Issue Summary

When I search "backend.tu.ts.egym.coffee" in the Bitbucket code search I retrieve inline code result that matched the string as shown in the screenshot 1.png

When I change the search to "tu.ts.egym.coffee" I retrieve only files whose name has "tu.ts.egym.coffee", it does not show the file which has words that match tu.ts.egym.coffee

Steps to Reproduce

1. In the code search, search for  backend.tu.ts.egym.coffee, it will show the file which has the string backend.tu.ts.egym.coffee. See screenshot 1.png
2. If you search for tu.ts.egym.coffee, it shows only files whose name has tu.ts.egym.coffee, but not the file which has the string backend.tu.ts.egym.coffee
   See screenshot 2.png

Expected Results

When you search for tu.ts.egym.coffee, it should show files whose name has tu.ts.egym.coffee and also the file which has the string backend.tu.ts.egym.coffee 

Actual Results

When you search for tu.ts.egym.coffee, it shows only files whose name has tu.ts.egym.coffee, but not the file which has the string backend.tu.ts.egym.coffee 

Workaround

1. Search for tu\.ts\.egym\.coffee instead of tu.ts.egym.coffee, ** it works as expected.

2. for the syntax with Class1.Class2RRRR, we suggest using the same syntax as a phrase search, in the following way: "Class1 Class2" this should help with finding the results you are looking for until our team addresses this issue.
