- Run `./gradlew :<subproject>:quickTest` where `<subproject>` is the name of the subproject you've changed. 
- For example: `./gradlew :launcher:quickTest`.

#### Install Gradle locally

and try out a change in behavior manually. 
- Install: `./gradlew install -Pgradle_installPath=/any/path`
- Use: `/any/path/bin/gradle taskName`.

Use this checklist to ensure a complete migration:

### Pre-Migration

- [ ] Assess current search system (document count, size, sources)
- [ ] Review infrastructure requirements
- [ ] Install and configure Fess (version: ______)
- [ ] Install compatible OpenSearch/Elasticsearch
- [ ] Backup current search system configuration
- [ ] Backup current search indices/documents
- [ ] Document current API endpoints and integrations

                          example: "Enterprise Search Server: <strong>Fess</strong> Commercial Support Open...Search Server: <strong>Fess</strong> What is <strong>Fess</strong> ? <strong>Fess</strong> is very powerful...You can install and run <strong>Fess</strong> quickly on any platforms...Java runtime environment. <strong>Fess</strong> is provided under Apache...Apache license. Demo <strong>Fess</strong> is Elasticsearch-based search"
