You will gain insight into the features and capabilities of Apache Solr, allowing you to make an informed decision as to whether it is the right search engine solution for your business.
Solr is an open-source application, and it helps in building search applications. Fast, scalable, and enterprise-ready are all qualities of Solr. It exposes Lucene Java APIs as REST-Full services. One can put documents in it (called indexing) via XML, JSON, CSV, or binary over HTTP, create the via HTTP GET, and receive XML, JSON, CSV, or binary results.
Due to its ability to index, search, and deliver recommendations for relevant information depending on the taxonomy of the search query, Solr is a popular search platform for websites. Additionally, its ability to index and search documents and email attachments makes Solr another well-known search engine for workplace searches.

Step 1: Indexing
Solr uses fields to index a document. Data is first put through a field analyzer, where Solr uses char filters, tokenizers, and token filters to make the data searchable before it is uploaded to the index. The string as a whole can change as a result of char filters. Tokenizers divide field data into lexical units, or tokens, which are then sent through filters that determine whether to maintain, change (such as by changing all of the data's case or eliminating word stems), delete, or even create new tokens. These last tokens are searched or added to the index at query time.
Step 2: Querying
Search phrases may include everything from keywords to photos to geographical information. For example, when a query is sent, Solr processes it using a query request handler (also known as a "query handler" ), which works similarly to an index handler except that it retrieves documents from the Solr index rather than posting them.
Step 3: Ranking the Results
The aptest hits are displayed at the top of the matched documents as Solr matches indexes documents to a query and rank the results based on relevance scores.
