How to analyze the principle of solr? in view of this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible method.

Solr provides standard http interface to add, delete, modify and query the index of the data. In Solr, users start indexing and searching by sending HTTP requests to Solr Web applications deployed in servlet containers. The Solr accepts the request, determines the appropriate SolrRequestHandler to use, and then processes the request. The response is returned in the same way through HTTP. The default configuration returns a standard XML response for Solr, or you can configure an alternate response format for Solr.

You can pass four different index requests to the Solr index servlet:

Add/update allows you to add or update documents to Solr. These additions and updates cannot be searched until they have been submitted.

Commit tells Solr that all changes made since the last commit should be searchable.

Optimize reconstructs Lucene's files to improve search performance. It is usually better to perform an optimization after the index is complete. If updates are frequent, optimizations should be arranged when usage is low. An index can run normally without optimization. Optimization is a time-consuming process.

Delete can be specified through id or query. Delete by id will delete the document with the specified id; delete by query will delete all documents returned by the query.
