MB-35347

Description

• Introduces the ability to index specialized "Synonym Documents" that function as a thesaurus within bleve. When a word is queried using the Match Query, this thesaurus is consulted to find synonyms for the queried word.
• This feature supports acronyms and multi-word synonyms when the indexed field has IncludeTermVectors set to true.
• All customizations for the Match Query are fully supported, including options like Fuzziness and the Operator. This means you can perform fuzzy matching on a word and find its synonyms within the index.
• You have the flexibility to define synonym sources using the AddSynonymSource API. Furthermore, you can associate any TextFieldMapping with a synonym source to use it during queries. Additionally, you can set a custom analyzer for the synonym documents, allowing you to use a single source of synonym documents with multiple analyzers attached to it, making it usable across various FieldMappings.
