Boolean logic queries are a powerful way to search for information in Apache Solr by combining multiple search terms using Boolean operators. Here's a brief overview of how to use Boolean logic queries in Solr:
1. 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" by using the query "Solr AND Lucene".
2. Use parentheses: When using multiple Boolean operators in a single query, it's important to use parentheses to ensure that the query is evaluated correctly. For example, you could search for documents that contain either "Solr" or "Lucene", but not both, by using the query "(Solr OR Lucene) NOT (Solr AND Lucene)".
3. Use wildcards: Solr also supports the use of wildcards to match variations of words. For example, you could use the query "Solr*" to match documents that contain words starting with "Solr", such as "SolrCloud" or "Solrj".
4. Use phrase searching: Solr allows you to search for exact phrases by enclosing the phrase in double quotes. For example, you could use the query ""Apache Solr"" to match documents that contain the exact phrase "Apache Solr".
5. Use range searching: Solr allows you to search for documents within a specific range of values 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, allowing you to match documents that contain similar words. For example, you could use the query "Solr

Boolean logic queries are a powerful way to search for information in Apache Solr by combining multiple search terms using Boolean operators. By using Boolean logic queries, you can construct complex queries that accurately match the information you’re looking for. The Solr documentation provides detailed information on how to construct Boolean logic queries for your specific use case.
