The ESRI GEO Portal provides many search options. To make the most of the ESRI GEO Portal capabilities, keep in mind the following tips for the search syntax:
A query is broken up into terms and operators. There are two types of terms:
Single Terms and Phrases. A Single Term is a single word such as air or quality.
A Phrase is a group of words surrounded by double quotes such as "air quality".
Terms may be combined together with operators to form a more complex query. To find content that contains both single terms whether they follow each other or not use air AND quality.
You can search in certain parts of the metadata. For example to search for items that contain the term WMS in the title of the metadata, use title:WMS.
Terms may be modified using a wildcard. For example to search for items that contain the term ortho anywhere in the metadata as a complete word or as part of a word, use ortho*.
