Quick Search Snippet

Copy/Paste the code below to include SDC "Quick Search" snippet on your website:

Web Services

Users can search SDC holdings via a REST based Web service. To invoke the Web service, simply add/replace the query parameter (fq) with any of the above defined SDC fields. Here is an example:
https://usgs.ornl.gov/sdcsolr/core1/select?fq=title:*Colorado*&q=*:*&start=0&rows=10&wt=xslt&tr=example_rss.xsl

Search response is in the ATOM XML format. Any RSS reader can be used to view the response or a custom view can be created from the response.
