LEO Network


The LEO Network advanced search engine supports many filtering options, as well as many options for viewing and downloading search results.

Query Options

Querying by Search Term

The most common way to limit your search results is to specify one or more search terms. The search engine performs a full-text search based on your search terms. Some example searches follow.

To search for a single word, simply enter it. For example:


To search for multiple terms, enter them separated by a space. For example:

dead whale

which is the same as:

dead | whale

Note that the query above will find posts containing the term whale or dead. However, posts contain both terms will score higher in the search ranking.

It is also possible to search for posts containing both terms, like this:

dead + whale

To find an exact phrase, surround it with quotation marks. For example:

"dead whale"

The query above will find posts containing the phrase dead whale, but posts containing only dead or whale will not be included.

Parentheses can be used to create complex queries. For example:

(elk | deer | moose | caribou | reindeer) + "wasting disease"

The query above will find posts containing the name of an ungulate, plus the exact phrase "wasting disease."

Finally, note that the search engine is not inflection-sensitive - for example, it treats plural and singular versions of words as being the same.

Filtering by Post Type (Observation or New Article)

By default, search results are limited to only first-person LEO Observations. Using the drop-down menu, you may change this to only News Articles, or both News Articles and Observations.

More Filtering Options

The Filters button allows you to specify addition filtering options, such as:

  • Topic - i.e. the LEO categories used to tag posts.
  • Date - including year, month, and season.
  • Geography - such as country or region.

Result Viewing Options

The results of your search query may be viewed in a variety of formats:

  • In a pageable list. This is the default format.
  • On a map. In this format, posts that have been geocoded will appear as pins on a map.
  • As thumbnails images. In this format, the "tile image" for each post is shown in a mosaic.
  • As a slideshow. In this format, you are able to page through each post in the resultset individually.
  • In a timeline. In this format, posts are arranged according to their date.
  • Summarized as statistics. In this format, individual posts are not viewable, but summary statistics are viewable, such as the number of posts with given topic tags.

In addition, search results may be downloaded in a number of different formats:

  • GEOJSON (two different ways, verbose and simplified)
  • KML (suitable for importing into Google Earth)
  • CSV (suitable for importing into Excel)
  • RSS
  • Atom
