Suggestion for wildcard field type

Roughly speaking leading infix queries (leading wildcard or .foo. regexes) have costs as follows:

  1. keyword fields are linear with the number of unique terms
  2. wildcard fields are linear with the number of docs that use a term

So if your URLs e.g. the site home page appear in many docs these are likely to be slow to match.
The flowchart at the end of this blog has a good decision chart.
