  -## How to limit where TechDocs Collator scanning the Software Catalog
  -
  -The DefaultTechDocsCollator is responsible for indexing the TechDocs into search.
  -The way it does is by getting all the entities every refresh interval from the
  -catalog and find the entities that has annotation `backstage.io/techdocs-ref`,
  -the process of getting all the entities is quite expensive if you have a large
  -amount of entity catalog data. To relieve the process, you can filter where the
  -DefaultTechDocsCollator is scanning your entities.

  -```typescript
  -indexBuilder.addCollator({
  - defaultRefreshIntervalSeconds: 600,
  - collator: DefaultTechDocsCollator.fromConfig(config, {
  - discovery,
  - logger,
  - tokenManager,
  -+ filter: {
  -+ kind: ['API', 'Component', 'Domain', 'System'],
  -+ },
  - }),
  -});
