Phrase match is one of the keyword matching options SearchIQ provided. It allows you to match user query in exact form from any of the fields indexed. For example, if user types “tennis shoes”, the posts/products contain “tennis shoes” with other terms before or after the phrase will be shown, but not for “shoes for tennis”, or “tennis sneakers”. Phrase match is more targeted than broad match and full term match.
However, if you feel this match option is too restricted. You can consider to use broad match and full term match. Both of these matching options support phrase match with quotes before and after the search query.
