Accession IDs associated directly and only with a genome feature appear as an exact match under Genome Features. Accession IDs associated with one or more genome features and with another object (for example, a sequence ID) return the associated features as exact matches and accessioned objects in Other Results by ID. These include:
In addition, some accession IDs are not unique. As an example, query for 100678.
You may use any of these, and more. Searchable fields for exact matching include:
Quick Search handles special characters such as parentheses, commas, colons, semicolons, dashes, slashes, +/-. However, the text in this example consists of both the symbol (T(XA1?;InY)8Ei) and name (reciprocal translocation, Chr X and inverted Chr Y, Eicher 8). Enter either the symbol or the name in the query box. If you want an exact match on the name/symbol combination, enclose each group in quotation marks ("T(XA1?;InY)8Ei" "reciprocal translocation, Chr X and inverted Chr Y, Eicher 8").
All synonym variations produce the same result. For example, whether you enter (K+ + H+)-ATPase activity or H+/K+-ATPase activity, or H,K-ATPase activity, you'll see identical matches.
The string above contains both the term definition (hydrogen:potassium-exchanging ATPase activity) and the identifier (GO:0008900). One or the other is sufficient when querying for any matches. For best results, enclose multi-word terms in quotation marks, e.g. "hydrogen:potassium-exchanging ATPase activity."
Quick Search looks for terms (that is, keywords), synonyms, and definitions from the vocabularies. If you want an exact match, put the word or phrase in quotation marks to find a complete term, synonym, or definition.

You can enter as many as 32 words, IDs, or other text items. Each piece of text in a phrase, even when enclosed in quotation marks, counts as a word.
The only wild card allowed is the asterisk and you can only use it at the end of a word or symbol or term.
Yes, as long as they do not contain more than 32 words.
No, but they are helpful when you want Quick Search to match an exact word, term, or phrase.
No. However, at the top of the Quick Search Results, anything that it does not find is highlighted in red, next to See Details for this Search. Frequently, this is a clue that a term is misspelled.
Yes. See Querying by Accession ID - Results and Examples for list of providers, sample IDs, and where to look for any matches in the Quick Search Results.
Quick Search identifies the "root" of a word by removing common suffixes. This is called stemming. (For more information, see stemming in Wikipedia.) As examples: translocation is stemmed to transloc-; immunization is stemmed to immun-. Click See Details for this Search on a Results page to see how Quick Search has stemmed any word or phrase in your search text.
Term Stemmed to... alimentary alimentari- perinatal perinat- metabolism metabol- immune immun- embryonic embryon- postnatal postnat- aging age- pigmentation pigment- urinary system urinari-, system- respiratory respiratori- tumorigenesis tumorigenesi-
Note: For best results, use wild cards on scientific or medical terms that the stemming algorithm may not recognize. As examples, use:
Note: You may find that matches on the Genome Features are to stemmed versions of your search term and that these entries appear prior to your search term. As an example, you enter Apoe and expect to see alleles of this gene at the top of the list, but instead you discover genes with synonyms containing Apo. This occurs because the search engine does not discriminate between Apo (the term as stemmed) and Apoe (your term) but does allot marker symbols a larger value.
Stop words are natural articles of speech that are filtered by search engines to speed up processing. See stop words in Wikipedia for a definition. Quick Search removes the following words (except when they are part of a gene name) from queries:
a | an | and | as | be | but | if | is| it | or | such | that | the | their | then | there | these | they | this | was | will
