The query history holds all the queries you have run and/or the lists of genes you have uploaded. From here you can view, delete and export your queries.
Ranking targets. once you have some queries, you can rank the genes by assigning scores (weights) to each query, and then combining the queries (Union). When the queries are combined, those genes present in more than one query will have their scores added. The result will be a new query, ordered by descending score/weight.
