Fielded search queries are a powerful way to search for information in Apache Solr by specifying the fields you want to search in. Here's a brief overview of how to use fielded search queries in Solr: 1. Specify the field to search in: To use a fielded search query in Solr, you need to specify the field to search in by using the field specifier syntax. For example, to search for documents that contain the word "Solr" in the "title" field, you would use the query "title:Solr". 2. Use Boolean operators: Solr supports Boolean operators like AND, OR, and NOT, which allow you to construct more complex queries. For example, you could search for documents that contain both "Solr" and "Lucene" in the "title" field by using the query "title:Solr AND title:Lucene". 3. Use wildcards: Solr also supports the use of wildcards to match variations of words within a specific field. For example, you could use the query "title:Solr*" to match documents that contain words starting with "Solr" in the "title" field, such as "SolrCloud" or "Solrj". 4. Use phrase searching: Solr allows you to search for exact phrases within a specific field by enclosing the phrase in double quotes. For example, you could use the query "title:"Apache Solr"" to match documents that contain the exact phrase "Apache Solr" in the "title" field. 5. Use range searching: Solr allows you to search for documents within a specific range of values within a specific field using range queries. For example, you could use the query "price:[10 TO 20]" to match documents with a "price" field between $10 and $20. 6. Use fuzzy searching: Solr also supports fuzzy searching within a specific field, allowing you to match documents that contain similar words. For example, you could use the query "title:Sol
” to match documents that contain words similar to “Solr” in the “title” field, such as “solar” or “soldier”.
Fielded search queries are a powerful way to search for information in Apache Solr by specifying the fields you want to search in. By using fielded search queries, you can narrow down your search to specific fields and improve the accuracy of your search results. The Solr documentation provides detailed information on how to construct fielded search queries for your specific use case.
