Abstract
One embodiment relates to a computer-implemented method for multiple-keyword matching performed using a computer including at least a processor, data storage, and computer-readable instructions. A keyword set and a text input to be searched are obtained. The keyword set is processed to create a reverse trie. A search procedure which starts from the end of the text is then applied using the reverse trie to find keyword occurrences in the text input. Other embodiments, aspects, and features are also disclosed.
