eggNOG uses a relational database system (PostgreSQL) to store primary data and precomputed orthologous groups.

General Search
Search types:	Protein names, COG names, Protein sequences (BLAST) and Full text
Search format:	Full text, protein name and COG name searches can be mixed with multiple search terms. The search terms must be on individual lines within the search box. The search box expands up to 20 lines. Sequence searches can either be a single sequence over multiple lines or multiple sequences in fasta format.
Comments:	Please note that multiple searches can take time and that sequence searches use our BLAST server and can take up to 10 minutes depending on the load and sequence size. Non sequence searches use human as the default species, but can be changed on the result page.

File Search
Search types:	Protein names, COG names, Protein sequences (BLAST) and Full text
Search format:	Full text, protein name and COG name searches can be mixed with multiple search terms and taxonomic ids. The search terms must be on individual lines within the uploaded file with one search term and taxonomic id pair per line and the search term and taxonomic id TAB seperated. Sequence searches must be in fasta format and are not taxonomic specific.
Comments:	Please note that multiple searches can take time and that sequence searches use our BLAST server and can take up to 10 minutes depending on the load and sequence size. Please do not upload fasta file with more than 30 records.
