How to choose search engine?
The following is a comparison of two search engines:
- fuse: simple, no need to synchronize- index.json, no limit for- contentLength, high performance
- lunr: simple, no need to synchronize- index.json, no limit for- contentLength, but high bandwidth and low performance (Especially for Chinese which needs a large segmentit library)
- algolia: high performance and low bandwidth, but need to synchronize- index.jsonand limit for- contentLength
