QuickSearch help

The QuickSearch tool on the home page provides access to the FlyBase report pages. By default QuickSearch scans Drosophila melanogaster (Dmel) genes for the search term. To search for genes in another species you should add a 4-letter species prefix to the gene name separated by backward slash "\" , for example Dvir\dpp, which will override the "Dmel only" option. The "All species" option enables you to look for a gene in all the species available. Data other than genes can be queried by selecting one of the options from the "Data Class" drop-down menu.

A search using the default "ID/Symbol/Name" option is case-insensitive and restricted to FlyBase IDs, valid symbols and synonyms, such as CG numbers, and names. If the "All text" option is selected the search will be more comprehensive but slightly slower. A unique match for the search string produces the relevant report page, whereas more than one match will generate a list of results linked to the report pages.

The wild card character (*) can be added to the beginning or the end of the search term to find all terms with the shared root. For example, an "All text" search of the genes data class for the term *meio* will identify genes that include 'meiosis', 'meiotic', 'premeiotic', or 'meiocyte' in some field. Similarly, searching stocks data for *bxd* will find stocks that carry either aberrations or alleles that include bxd in the genotype.

QuickSearch Hints & Examples
hide Boolean Searches - AND, OR, NOT

QuickSearch does not support Boolean operators at present. For a more powerful search tool please try QueryBuilder, which allows queries on a field-by-field level. QueryBuilder also enables complex queries involving combinations of fields, such as searching for genes annotated with particular GO biological processes that interact with particular genes.

hide Find me the Adh gene in Drosophila pseudoobscura

The best strategy would be to type 'Dpse\Adh' into the "Enter text" box, which will take you directly to the report page of the gene. Dpse is the 4-letter species abbreviation for Drosophila pseudoobscura, and the backward slash "\" is used as a separator between the 4-letter abbreviation and the gene name. Alternatively, you could enter 'Adh' into the search box with the "All species" option selected, and then choose the Drosophila pseudoobscura gene from the resulting list.

hide Find me all the Drosophila melanogaster genes that start with "dp"

Click the "Dmel only" button and type "dp*" into the "Enter text" box.

hide Find me all the references associated with "Muller"

Select the data class "references" and type "Muller" into the "Enter text" box.

hide Searching for GAL4 and GFP Lines

Select the data class "stocks" and enter the search term surrounded by wild card characters, for example *GFP*. We recommend using wild card characters because often the search term may be part of a more complex term such as P{w[+mC]=UAS-GFP.nls}8.

hide Searching for Stocks of Specific Alleles

Select the data class "stocks" and enter the allele as the search term with the superscript placed in square brackets, for instance type "bcd[1]" to search for bcd1.
