On this page you will find additional information to help you use the site features to access data through
the National Geothermal Data System (NGDS)
Search Tool
The NGDS text search tool is the primary method for finding specific metadata records.
A full text search of NGDS metadata is performed for each search.
Search TextBox Functions
Type Ahead - After entering 3rd character in the search textbox, typeahead terms will appear, allowing for autocomplete,
using NGDS keywords as source.
Search History - when the search textbox is in focus, the search history listbox appears with previous entered search terms (saved locally).
Note: Individual terms may be removed from the search history list by click on the "x" button in front of the term.
Doubleclick - clears textbox contents.
Return - is the same as clicking the search button.
Sort - by Modified Date, Relevance, Name ascending, Name descending
Clear - button will clear your search history
Saved - Show saved records

Search Map Tool
The Search map provides location data for those records with location data included in the metadata
and allows users to search records by location.
Viewing search results location data - when a text search is performed, any records on the currently selected page
with location info will appear in the map as a marker. Click on the location marker to display the Title,
clicking on the title will show the record detail page.
When mousing over search result records, each record will be highlighted in the map as it moused over.
Searching with the Map - Using map pan and zoom zoom functions, set the extent and center
of the search area location
of interest, then click on "Search using Map Extent" button to return results. Note: This returns only
records that have location info included in the metadata record.

Facets - are preselected Search Topics
For each category only the item with the top 5 hits will appear in display,
except for catalogs, which displays all.
Facets selections appear for the current selected search results, if
searches have been run, facets appear for all data.
Authors - Filter results by publication Author
Data Types - Filter results by the data type of associated dataset.
Catalogs - Filter results by the originating collections for NGDS metadata records.
Content Models - are defined data formats for those records that include
geospatial data.
