Consecutive characters return more matches than expected

[mauricioszabo]

Description

If I filter for strings like aaaaa or tttt it returns more items than expected, both with filter and with ObjectArrayFilterer (didn't tested other filtering methods)

Steps to Reproduce

const z = require('zadeh')
z.filter(['one two', 'It is a test'], 'aaaaaa')
// => Returns ['It is a test'], even when there's only one "a" on it

Expected behavior:

To return nothing

Reproduces how often:

100%
