Hello,

Is there a way to count the number of occurrences of the query in target strings?
For example, if I do

writer = pysubstringsearch.Writer(
    index_file_path='output.idx',
)

writer.add_entry('string_string')
writer.finalize()
reader = pysubstringsearch.Reader(
    index_file_path='output.idx',
)

and I then

reader.number_of_occurences('str')

I would want to receive 2. Can I do it?
My (indexes) text is very large (hundreds of millions of characters) and queries are rather large too (can be up to a million character).

Thanks

In the search function, is there any support to search using regular expression ?

does it support for search by multiple substring? like (?:substring1|substring2|substring1) in regex

is it possible to apply boundary match in multiple search?
or anyone have recommendation library that have feature like that in fast execution?
