filter_by parameter not working

Description

Hello,
filter_by parameter not working on my docusaurus site.

I want to ignore anchor:shorcut-product on search result(See all result page). Even if I set the parameters, the result is the same.

config is follwing:

typesenseSearchParameters: {
  filter_by: 'anchor:!=shortcut-product',
  highlight_affix_num_tokens: 200,
},

refer to the following dataset:

{
  "anchor": "shortcut-product",
  "docusaurus_tag": "docs-default-current",
  "hierarchy": {
    "lvl0": "...",
    "lvl1": "WhaTap Docs",
    "lvl2": null,
    "lvl3": "상품별 문서 바로가기 ​",
    "lvl4": null,
    "lvl5": null,
    "lvl6": null
  },
  "hierarchy.lvl0": "...",
  "hierarchy.lvl1": "WhaTap Docs",
  "hierarchy.lvl3": "상품별 문서 바로가기 ​",
  "hierarchy_camel": [
    {
      "lvl0": "...",
      "lvl1": "WhaTap Docs",
      "lvl2": null,
      "lvl3": "상품별 문서 바로가기 ​",
      "lvl4": null,
      "lvl5": null,
      "lvl6": null
    }
  ],
  "hierarchy_radio": {
    "lvl0": null,
    "lvl1": null,
    "lvl2": null,
    "lvl3": "상품별 문서 바로가기 ​",
    "lvl4": null,
    "lvl5": null,
    "lvl6": null
  },
  "hierarchy_radio_camel": {
    "lvl0": null,
    "lvl1": null,
    "lvl2": null,
    "lvl3": "상품별 문서 바로가기 ​",
    "lvl4": null,
    "lvl5": null,
    "lvl6": null
  },

  "weight": {
    "level": 70,
    "page_rank": 0,
    "position": 5,

  }
}

and url is not exist, why is such a value generated?

Typesense Version: 2.4.1

OS: linux

Start at the Docusaurus search configuration entry point that consumes typesenseSearchParameters, then trace how filter_by and generated anchor records are passed to Typesense. Reproduce the supplied filter and dataset; done when the shortcut-product record is excluded from all-results searches and the source of the generated anchor is identified.
