| std::unique_ptr< Iterator > clang::clangd::dex::Corpus::all | ( | ) | const |
Returns TRUE Iterator which iterates over "virtual" PostingList containing all items in range [0, Size) in an efficient manner.

| std::unique_ptr< Iterator > clang::clangd::dex::Corpus::boost | ( | std::unique_ptr< Iterator > | Child, |
| float | Factor | ||
| ) | const |
Returns BOOST iterator which multiplies the score of each item by given factor.
Boosting can be used as a computationally inexpensive filtering. Users can return significantly more items using consumeAndBoost() and then trim Top K using retrieval score.

| std::unique_ptr< Iterator > clang::clangd::dex::Corpus::intersect | ( | std::vector< std::unique_ptr< Iterator >> | Children | ) | const |
Returns AND Iterator which performs the intersection of the PostingLists of its children.
consume(): AND Iterator returns the product of Childrens' boosting scores.

| std::unique_ptr< Iterator > clang::clangd::dex::Corpus::limit | ( | std::unique_ptr< Iterator > | Child, |
| size_t | Limit | ||
| ) | const |
Returns LIMIT iterator, which yields up to N elements of its child iterator.
Elements only count towards the limit if they are part of the final result set. Therefore the following iterator (AND (2) (LIMIT (1 2) 1)) yields (2), not ().

Returns FALSE Iterator which iterates over no documents.
