This workflow demonstrates the Indexing & Searching plugin for address database cleansing. It uses fuzzy queries to identify typos in a given address data base. First an index is created on the data table. Once the index has been created it can be queried using a powerful query language. The query syntax bases on the Lucene query syntax and supports among others phrase queries, wildcard queries, fuzzy queries, proximity queries, range queries, term boosting, grouping and boolean operators.
