ARB_NT/Genome/Search and Query

DESCRIPTION
This describes the search feature in ARB. When we talk about 'items' below, we mean e.g. 'species', 'genes', etc., depending which search tool you are currently using.
| |
|
SEARCH FIELD
Each search expression applies either-
to a specific item field (e.g. 'full_name') or
-
if you select the '[any field]' pseudo search field, all direct database subentries of the item are searched for the expression. This does NOT work for subcontainers (i.e. 'ali16s/data' is not searched).

SEARCH EXPRESSIONSORTING RESULTS
Search results are displayed unsorted by default. You can sort them, by selecting a different order with the sort radio button. The available sort criteria are
unsorted display items like they are stored in database
by value sort by content of first query field
by id sort by unique item id (e.g. 'name' for species)
by parent sort by globally unique id of parent item (e.g. 'name' of organism for genes)
by marked sort marked before unmarked items
by hit sort by (and display) hit description (the hit description tells you
why an item was hit by query)
reverse reverts previously selected sort order
ARB remembers and uses all the sort criteria you apply.
Example: Selecting 'by id' will sort the items by their id (e.g. 'name'). If you select 'by value' afterwards, ARB will sort items by the content of the first query field - if the contents of some items are equal, it will still sort them by name.

NOTES
Wildcarded or exact search always searches case insensitive. Regular expression search always searches case sensitive.

EXAMPLESWARNINGS
Using ACI is a bit tricky here, cause you cannot see what happens. Using 'trace(1)' somewhere in the ACI expression starts to print an ACI trace to the console. Don't forget to use 'trace(0)' afterwards, otherwise that may slow down ARB.
