I looked at reversed wild card filter but think that the regular wild card matching as opposed to leading wild card matching is better suited for an auto-completion feature. > We do auto-complete through prefix searches on shingles. > Just to confirm, do you mean using EdgeNgram filter to produce letter ngrams of the tokens in the chosen field? Assuming the regular wild card query would also work, any thoughts on how it compares to the EdgeNGram approach in terms of added indexing cost, performance, etc.? Thanks a lot for your valuable inputs/comments. Prasanna.
