java: how to limit score results in mongo - text-search

Question

I have this mongo query (java):
TextQuery.queryText(textCriteria).sortByScore().limit(configuration.getSearchResultSize())
which performs a text search and sort by score.
I gave different wiehgt to different fields in the docuemnt, and now I'd like to retrieve only those results with score lower then 10.
is there a way to add that criteria to the query?
this didn't work:
query.addCriteria(Criteria.where("score").lt(10));
if the only way is to use aggregation - I need a mongoTemplate example for that.
in other words
how the do I translate the following mongo shell aggregate command, to java spring's mongoTemplate command??
can't find anywhere how to use the aggregate's match() API with the $text search component (the $text is indexed on several different fields):
db.text.aggregate(
[
{ $match: { $text: { $search: "read" } } },
{ $project: { title: 1, score: { $meta: "textScore" } } },
{ $match: { score: { $lt: 10.0 } } }
]
)
Thanks!

Please check with below code sample, MongoDB search with pagination code in java
BasicDBObject query = new BasicDBObject()
query.put(column_name, new BasicDBObject("$regex", searchString).append("$options", "i"));
DBCursor cursor = dbCollection.find(query);
cursor.skip((pageNum-1)*limit);
cursor.limit(limit);
Write a loop and and call the above code from loop and pass the values like pageNum starts from 1 to n and limit depends on your requirement. check the cursor is empty or not. If empty skip the loop if not continue calling the above code base.
Hope this will be helpful.
