Hi. I am trying to make a NGramPhrase query that could tolerate terms missing, so even if one of the NGrams doesn't match it still gets picked up by search. I know I could use the combination of normal SpanNearQuery and a BooleanQuery, but it requires me to consider every possible pair of terms (since any one of the terms could be missing) and it gets too messy and expensive.
What I want to try is to use SpanTermQuery to get the positions of the mathcing NGrams and list the spans' position informations in an order, so that I could pick up any two or more spans near each other to score them accordingly, but I can't figure out how can I combine the spans. Any help in solving this issue is appreciated. Also, if there is an example of a simple scoring implementation example that combines multiple queries' results, it would be very nice.
