Hi Navin,
these characters are not searchable by the full-text-index.
@$# and other special-characters are treated as word-breakers[1] and can’t be
searched for.
If you ran for example the following query:
> ft:tokenize("f...@bar.de#test$baz“)
You will see which tokens will be added to the full-text-index.
The full-text-index is usually used to search in natural language texts, so
punctuation und special characters are generally ignored.
Maybe a naïve approach already helps:
> db:open(‚database')//text()[contains(., "@")]/..
