FTSearch that looks for '-'

Question

does anybody know if there is a possibility to search for '-' using FTSearch?

Set col = db.ftsearch({ [services] = "-"}, 0)

dat requests does not work and instead says:

Notes error: Full text error; see log for more information ( [services] = "-")

Answer 1

Short answer is no.

The full text search treats most symbol characters as a white space. The exception is if the search term itself is wrapped in quotes.

The FT search engine also uses 3-gram for searching. This means that less then 3 characters will not return the results you expect. White spaces would be treated in that search, but only in the context of the found text.

For example: "ce " would find "space " but not "space." or "space" or "spaced".

If you are looking for the field that only contains "-", then a better solution is to create a view with a column containing that field value, and/or filter by that field being that value.

Looks like you are trying to do a full text search in a view? You probably would get better response time and less server impact to use @Formula language if you are working with a view.

I try to keep away on doing full text searches on the entire database. You can use a search on a view collection for faster results. There is no restriction on how many views you can have in a db. There is a cost for everything though. There are so many little tricks that can be used to get better results. Please give us more details on what you are trying to do.
