I am working with a postcode shapefile which has over 8000 attributes and wish to search for particular attributes without having to scroll through thousands of others, is there a way of searching and selecting particular attributes?
Use the Select by Attributes tool (Select menu -> Select by attributes). Then Select the attribute you want to search by, the operator (=, <, >, etc), and the attribute you want to search for to build your query. It can either create new selections or add to existing selections.
Once you've selected the required features, you can do Select menu -> Zoom to selected. Or you can open the attribute table (right click the layer in the TOC and choose Open Attribute table), and then change the display to Selected features only. That will display just the features that were selected.
