Hi, I am wondering if we can use elastic search to do multi-level indexing, for example: if I want to index text like: "Lookup by an arbitraty identifier in MSMQ" Obviously, with the standard analyzer, it could be tokenized like "Lookup", "by", "an", etc But what if in addition to index each token (word), I also want to index n-gram phrase, like "Lookup by an", "by an arbitraty", "an arbitraty identifier", etc I saw elasticsearch has some n-gram options, but looks like the n-gram is made up by n char, "Loo", "ook", "oku", "kup", etc which are not n-gram phrases made up by n tokens(word) -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
