在Lucene中搜索确切的短语

Question

I have a single table of 10 GB in MySQL. The table consists of data about the suppliers, products and contracts. I am indexing the data using Lucene and to make the search faster. I have many conditions on which I filter my data like Supplier name, product name or contract Number or combination of any two.

The issue is Example: When I am searching for Products by entering the supplier name. Let the supplier name be "Company of Clothes". What I am getting is a list of products supplied by "Company of Clothes", "Company of Shoes","Company of bags" and not only the products supplied by the "Company of Clothes". How can I make Lucene search for only the exact word/phrase I entered.

Answer 1

I assume you are using the QueryParser to construct your queries. You may find it helpful to give a read to the query syntax documentation .

You can use a phrase query, by surrounding your query with double quotes:

"Company of Clothes"
