I have added a new field to each document in my index containing substrings of another field to speed up initial-wildcard searches.
Each document has a field "text" which might contain "the quick brown fox jumped over the lazy dogs" The new field - "text_substrings" would then contain "the quick uick ick brown rown own fox jumped umped mped ped over ver the lazy azy dogs ogs" This allows me to convert initial wildcard queries "*own" into a term query "own". However adding this field has exactly doubled the size of the index. Given that the term list is a small fraction of the index (?), I find this strange. I think it might be storing the documents twice. Is there any way to stop this from happening? Thanks Greg Tarr This message should be regarded as confidential.
