Type in the search string/formula using logical connectors (AND, OR) and curly brackets (instead of parantheses); the name of each searched receptor should be enclosed in brackets - for example: [hTAS2R10] if you want to search for a single receptor or {[hTAS2R10] OR [hTAS2R14]} AND [hTAS2R46] if you want to set more complex search criteria. Type hTAS1R2/TAS1R3 for the human sweet taste receptor. Type hTAS1R1/TAS1R3 for the human umami taste receptor. Instead of the initial h, put f, m or r for the fish, mouse or rat variant, respectively.
