Why I got 7 results for "6531 148 str" but no results for "6531 148 st"?

Is it because there are more than 50 terms in the sorted term dictionary between "st" and "str" based on [https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-match-query-phrase-prefix.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-match-query-phrase-prefix.html)? And for each of those terms, there is no search result?

Thanks!

Yes, that could very well be it. There could be many more than 50 terms that start with `st` and as a result you may miss out on `street`. You could try increasing `max_expansions` to a higher number, but keep in mind that this will make the query more expensive.
