Question

Similar to SQL I want to be able to search for terms, but instead of matching exact terms I want to be able to match terms that contains certain string say "abc".

Something like SQL's LIKE "%abc%"

At the moment I have the full term matcher like:

        AndFilterBuilder andFilter = FilterBuilders.andFilter();
        andFilter.add(FilterBuilders.rangeFilter("@timestamp").gt(start).lt(end));
        andFilter.add(FilterBuilders.termFilter("@host", "abc"));

Is there a way to do that? Regex may be?

Answer 1

尝试使用此：

andFilter.add(FilterBuilders.regexpFilter("@host", "*abc*"));
