1. A method comprising: receiving, by an entity extraction computer, a user input of partial search query parameters from a user interface, wherein the partial search query parameters having at least one incomplete search query parameter, wherein the user interface is presented on a user computer; extracting, by the entity extraction computer, in real-time, as search query data is requested by the user computer, one or more first entities from the partial search query parameters by comparing the partial search query parameters with an entity co-occurrence database having instances of co-occurrence of the one or more first entities in an electronic data corpus and identifying at least one entity type corresponding to the one or more first entities in the partial search query parameters, wherein a score is assigned to each extracted feature, wherein the score indicates a level of certainty of the each extracted feature being correctly extracted with a correct attribute; selecting, by a fuzzy-score matching computer, in real-time, as the search query data is requested by the user computer, a fuzzy matching algorithm for searching the entity co-occurrence database to identify one or more records associated with the partial search query parameters, wherein the fuzzy matching algorithm corresponds to the at least one identified entity type, wherein at least one of the entity extraction computer or the fuzzy-score matching computer comprises a main memory storing an in-memory database which comprises the entity co-occurrence database; searching, by the fuzzy-score matching computer, in real-time, as the search query data is requested by the user computer, the entity co-occurrence database using the selected fuzzy matching algorithm and forming one or more first suggested search query parameters from the one or more records based on the search; presenting, by the fuzzy-score matching computer, the one or more first suggested search query parameters to the user interface; receiving, by the entity extraction computer, a user selection of the one or more first suggested search query parameters from the user interface so as to form completed search query parameters; extracting, by the entity extraction computer, one or more second entities from the completed search query parameters; searching, by the entity extraction computer, the entity co-occurrence database to identify one or more entities related to the one or more second entities so as to form one or more second suggested search query parameters; and presenting, by the entity extraction computer, the one or more second suggested search query parameters to the user interface.
