String filter not working with pluginQPS

[FabioNappi]

Describe the bug

I have an Orama db with a string property in its schema and the QPS plugin enabled. When I perform a search with an array valued where clause on the string property (just like the second example in the docs) it finds no documents.

To Reproduce

1. initialize orama with QPS plugin

create({
  schema: {
    title: 'string',
    category: 'string',
  },
  plugins: [pluginQPS()],
})

2. insert documents
3. search documents in the db

orama.search(db, {
  term: 'Harry',
  where: {
    category: ['movie', 'book']
  }
})

4. the result is no documents found

Expected behavior

I expect to actually find documents with category = 'movie' OR category = 'book', but got none.

Environment Info

OS: MacOS 15.4
Node: 22.14.0
Orama: 3.1.6

@allevo any idea?

[allevo]

Hi! No idea. Can you also give us some documents you insert?

[FabioNappi]

Hello! Here it is a complete code snippet example to reproduce the bug. If you try to comment the plugin line, the search will actually return both documents

import {create, insertMultiple, search} from '@orama/orama'
import {pluginQPS} from '@orama/plugin-qps'

const db = create({
  schema: {
    title: 'string',
    category: 'string',
  },
  plugins: [pluginQPS()],
})

await insertMultiple(db, [
  {
    title: `Harry Potter and the Philosopher's Stone`,
    category: 'movie',
  },
  {
    title: 'Harry Potter and the Chamber of Secrets',
    category: 'book',
  },
])

const found = await search(db, {
  term: 'Harry',
  where: {
    category: ['movie', 'book'],
  },
})

console.log(found)

@allevo is there any news?

I've found that the pluginQPS doesn't even match Orama's own types:

Type 'OramaPluginSync' is not assignable to type 'OramaPlugin'.
  Type 'OramaPluginSync' is not assignable to type 'OramaPluginSync<unknown>'.
    Types of property 'beforeInsert' are incompatible.

The docs are wrong:

import { create } from '@orama/orama'
import { pluginQPS } from '@orama/plugin-qps'

const db = create({
  schema: {
    title: 'string',
    description: 'string',
    rating: 'number',
  },
  plugins: [pluginQPS()],
})

I believe this is the correct usage:

import { create } from '@orama/orama'
import { pluginQPS } from '@orama/plugin-qps'

const db = create({
  schema: {
    title: 'string',
    description: 'string',
    rating: 'number',
  },
  plugins: [pluginQPS],
})

@niltonheck @raiindev @micheleriva Any comment?

Hey, with the new v3.1.10 of the @orama/plugin-qps, it should work fine.

Closed as fixed in v3.1.10
