Hello, These results are the expected results. The location on ChrX is the default starting position for the Mar. 2006 (hg18) assembly (not a random location).
There are two display characteristics to alert a user that a "track data point" search query was not found. 1) The text at the top of the result page stating that the search string was not found in any tracks. 2) The data point's label is not highlighted with a black box in the genome graphic (applies to queries against track contents: genes and other features). Note: For a successful search, the data point's label would be highlighted to bring the user's attention quickly to the region of interest. For failed "position" searches, there is only one display characteristic. 1) The text at the top of the result page stating that the search string was not found is displayed. Note: Failed position searches may be due to an incorrectly formatted query or accidentally using the wrong assembly/species browser. Each assembly's gateway page has example queries and a link to the list of the assembly base sequence names/lengths (chromosomes, scaffolds, etc.). The text stating that a query failed is not as obvious as it could be. Internally, the group is discussing alternate display options.
