8. A system, comprising: one or more processing units comprising hardware; and memory comprising instructions that when executed by at least one of the one or more processing units perform a method comprising: matching a first target term, comprised in a target string, to a first known term in an index tree, the first known term associated with a known string identifier (ID); matching a second target term, comprised in the target string, to a second known term in the index tree, the second known term associated with the known string ID; and responsive to determining that a threshold number of target terms, comprising the first target term and the second target term, comprised in the target string are respectively matched with a known term associated with the known string ID, matching the target string to a known string associated with the known string ID.
