Help on Interface Screens : 3.37. Detailed Document Search Form

The Detailed Document Search Form allows you to get a uniform set of detailed descriptions for one or more data sets and related entities, containing information suitable for determining the location and content of each data set and its potential usefulness for a specific application. Select this option if you would like detailed descriptions in document format for system valid keywords.

A detailed document search can be done on any high level attribute or for specific data sets. You must limit the search with at least one attribute from one or more of the following categories: campaign, data center, data set, parameter, sensor, or source. You can also search for any string within the documents by entering a text string and starting a search.

This search will provide you with a single list of documents from all the data centers which are believed to have the appropriate information. The relevance of each document is a rough measure of how well the document is believed to match your search criteria. Relevances range from "highest" (best matches) to "very low" (worst matches). Several other items - the number of lines and bytes in the file, last update - are also provided when available.

If you compose a search that consists of only Parameter attribute selections the search will retrieve documents of type "data set". This is because the documents describe specific collections, instruments, etc., but are not written about a specific parameter.

Choose keywords from one or more categories

• You must specify at least one of campaign, data center, data set, parameter, sensor or source. The form will not let you proceed until at least one has been specified. A boolean 'or' is placed between values selected within a single attribute,and a boolean 'and' between attributes.

  As an example, say we choose Parameters: ATMOSPHERIC PRESSURE, SEA SURFACE TEMPERATURE; Sensor: ACCELEROMETER; and Data Center: JPL. This would be assembled as

  (Parameter=ATMOSPHERIC PRESSURE or Parameter=SEA SURFACE TEMPERATURE) and (Sensor=ACCELEROMETER) and (Data Center=JPL).

• There are no geographic or temporal limits for a detailed document search.

Type in text

A second way to create a detailed document search is to enter the text you want to search for as keywords and/or phrases in the scrolling text box.

• Keywords are single words: ozone, FIRE, MODIS.

• Phrases are words in quotes: "SEA SURFACE TEMPERATURE", "THEMATIC MAPPER".

You may use boolean connectives to make more complex searches. Items OR'ed together will select documents containing any of the items. Items AND'ed together will select documents containing all of the items. For example:

• FIRE - will select documents containing references to the First ISCCP Regional Experiment (FIRE) and any other documents containing this string.

• "THEMATIC MAPPER" - will select documents containing the phrase THEMATIC MAPPER.

• GSFC or LARC - will select documents containing references to either GSFC or LARC.

• (OZONE or "ICE MOTION") and (GSFC or NSIDC) - will select documents containing both a reference to either ozone or the phrase "ice motion" and references to either GSFC or NSIDC.

Max Detailed Documents per data center: The maximum number of documents to return for a detailed document search per data center.

Query Name: The name the system will try to give to the query when you save the query (download) to your local machine. Note, that some versions of Microsoft Internet Explorer ignore this and create their own bizarre file names.

Start Search

Once you've specifed a campaign, data center, data set, parameter,sensor, source, or text string, or a combination of these, click the "Start Search" button to start your search.

Upload/Download a Query

This function is at the bottom of the page. If you've named your query, you can download a copy of it to your local machine and save it by clicking on the Download query button. If you've already got a saved query, you can click on the browse button to show the browser where your query is and then upload it with the Upload Query button. The search type will be set to your current selection and not the search type from the uploaded file.
