Searching a value in a specific field in MongoDB Full Text Search
full-text-search, mongodb, mongodb-java
Solution
If you want to index a single field and search for it then it is the way it works by default. Lets say you want to index the field `companyName`. When you perform `$text` search on this collection, only the data from the `companyName` field will be used because you only included that field in your index.
Now the second scenario, your `$text` index includes more than one field. In this case you cannot limit the search to only look for values indexed from a specific field. The `$text` index is constructed on the collection level and a collection can have at most one `$text` index. Your option to limit search on specific field in this case may be to use `regex` instead.
MongoDB has the flexibility to fulfil requirements of other scenarios, but you can also evaluate using other technologies if your application is heavily search-driven and you are primarily after a full-text search engine for locating documents by keyword with a rich query syntax. ElasticSearch might be an alternative here. It really depends on the type of the application and your needs.
Problem
(MongoDB Full Text Search) Hello, I have put some fields in index and this is how I could search for a search_keyword. ``` BasicDBObject search = new BasicDBObject("$search", "search_keyword"); BasicDBObject textSearch = new BasicDBObject("$text", search); DBCursor cursor = users.find(textSearch); ``` I don't want search_keyword to be searched in all the fields specified in the index. *Is there any method to specify search_keyword to be searched in specific fields from the index??* If so, please give me some idea how to do it in Java. Thank you.
