Proximity Search #256

Closed 3CE8D2BAC65BDD6AA9 closed 2 years ago

Does Flexsearch have proximity search.

A proximity search looks for terms that are within a specific distance from one another.

To perform a proximity search, add the tilde character ~ and a numeric value to the end of a search phrase. For example, to search for a "apache" and "jakarta" within 10 words of each other in a document, use the search:

"jakarta apache"~10

The distance referred to here is the number of term movements needed to match the specified phrase. In the example above, if "apache" and "jakarta" were 10 spaces apart in a field, but "apache" appeared before "jakarta", more than 10 term movements would be required to move the terms together and position "apache" to the right of "jakarta" with a space in between.

@3CE8D2BAC65BDD6AA9 did you ever find a JS search library which suits your needs? I'm also looking for phrase and proximity searches.

To limit by distance you should use the "contextual index" feature by settings depth to the maximum distance you need to support (lower is better): https://github.com/nextapps-de/flexsearch#enable-contextual-scoring
