Apache Solr provides a powerful query language called SOLRQL (Solr Query Language) that allows you to query your Solr index using a wide range of search criteria. Here are some examples of how to use SOLRQL to query your Solr index:
1. Basic query: To perform a basic query, simply enter a search term into the Solr query box. For example, to search for all documents that contain the word “Solr,” you would enter the query “Solr” into the query box.
2. Field search: You can also search for documents based on specific fields within the document. For example, to search for all documents that have “Solr” in the “title” field, you would enter the query “title:Solr” into the query box.
3. Boolean operators: SOLRQL supports Boolean operators such as AND, OR, and NOT, allowing you to create complex queries. For example, to search for all documents that contain both “Solr” and “Lucene,” you would enter the query “Solr AND Lucene” into the query box.
4. Phrase search: You can search for exact phrases by enclosing the phrase in double quotes. For example, to search for all documents that contain the exact phrase “Apache Solr,” you would enter the query “”Apache Solr”” into the query box.
5. Wildcards: SOLRQL supports wildcards, allowing you to search for variations of a word. For example, to search for all documents that contain words starting with “Sol,” you would enter the query “Sol*” into the query box.
6. Range queries: You can search for documents within a specific range of values using range queries. For example, to search for all documents with a “price” field between $10 and $20, you would enter the query “price:[10 TO 20]” into the query box.
These are just a few examples of how to use SOLRQL to query your Solr index. SOLRQL provides a wide range of advanced features and configuration options, allowing you to build powerful search applications that meet the needs of your users. The Solr documentation provides detailed information on how to use SOLRQL to query your Solr index for your specific use case.
