Hi Does Elastic search have a capability of reading a text file containing `pattern = replacement` strings, and if any terms in the search query match `pattern` they are replaced with the boolean expression defined on the right side of the equals... e.g. rowing boat = (rowingboat\* OR "row boat\*" OR (rowing\* AND boat\*)) I'm new to Elastic search, still only reading through docs to understand it, but I can't find any reference to anything that looks like it does this? ---
