1. If I choose the same ontology class twice in the Simple Retrieval search, the search will only match that class once. Why?

The Simple Retrieval engine will not count more than one occurrence of an ontology class. In other words, if you select the same ontology class more than once, this ontology class will still be only matched once. This is to facilitate a faster search. Choosing to search for the same ontology class more than once is a feature reserved for the more advanced retrieval systems ( Advanced Retrieval and Fact Extraction )!

2. What does CGC stand for?

CGC stands for Caenorhabditis Genetics Center which is based at the University of Minnesota in Minneapolis. One of the functions of the CGC is to maintain a bibliography of journal articles which are information rich in C. elegans biology. Each paper in this bibliography is assigned a "CGC number", e.g. cgc1234. Currently the CGC collection stores ~6,000 papers dating back to 1978. The CGC bibliography comprises the core paper collection for a number of databases used by the C. elegans community, including Leon Avery's C. elegans web server , Wormbase and of course Textpresso . We have also augmented the Textpresso bibliography with PubMed papers pertaining to C. elegans biology but not in the CGC bibliography (represented by the accession number pmid1234567).
