title: How to stop . being treated as a separator in SQLite FTS4
body: <p>I want to be able to search for numbers like 2.3 using FTS4 in SQLite, but the . is being treated as a token boundary. Short of writing a full bespoke tokenizer is there any other way of excluding the . from the list of token boundary characters?</p>
  
  <p>Being able to search for decimal numbers seems like a common use case, but I can't find anything relevant on SO / Google. My best solution at present is to replace all . chars in the text with a known (long) string of letters and substitute accordingly on each search...</p>
