A method of providing predictive search query recommendations for a search query. The method can be implemented via execution of computer instructions configured to run at one or more processing modules and configured to be stored at one or more non-transitory memory storage modules. The method can include receiving the search query from a user. The method also can include determining the predictive search query recommendations for the search query using a tree data structure. At least one top layer of the tree data structure can include at least one trie query node and bottom layers of the tree data structure can include ternary tree query nodes. The method further can include sending the predictive search query recommendations to the user. Other embodiments of related systems and methods are also disclosed.
