Enter text search terms in the search field then press the Search Button to progress to the next tab.

Text can consist of one or more words, either on one or more lines. The search text can also include tabs. All tabs and new line characters that are entered will be converted to spaces. This allows the copying and pasting of text from various applications.

Auto-complete is based upon all the words within Gataca that appear in the name, description, and definition from all concepts. When the drop-down list appears, use the arrow keys or mouse to to make a selection, then use TAB or ENTER to apply it. To cancel an auto-complete selection, press ESC, and then the TAB and ENTER keys will behave normally.

The last 10 Text Search Queries are stored and are accessible under the Session History tab.

For examples on how to use boolean logic, grouping, proximity searches, or even fuzzy searches please click on the Examples tab.

These filter results are grouped first by category with the default being All Categories.

Within each category's filter set, there exists multiple filter groups that have a list of filter topics. The filter topics are based upon the search terms that have been entered on the Text Search tab and the number in parenthesis represents an approximate concept count that share the same value.

Clicking on the concept count will apply that filter and take you to the next tab, the Search Results. Otherwise after selecting filters, click on the Next button to go to the Search Results tab to see the results of the text terms with the applied filters.

For more information about filtering, please see the side bar below titled Notes On Filters or Help topics of Filters and Filters - Try it! .

• Click the Next button to view the Text Search Results.
• Gataca contains data from many data sources of which similar data is group together in to Categories. Each category may have data elements that are not found in other categories and they may also share similar types of data. Any data element (field, column, data type, etc...) that has a fairly small set of unique values (generally no more than 30) for the whole category can be used as a filter (facet) to help zero in on interesting data.
• Each category has its own set of filters that can be set under the pane Category Being Filtered. The category of ALL is a general set of filter groups that apply to all categories. If there are any filters enabled for a given category then their count will be shown after the category name.
• Filters are listed by topics and these topics comprise a filter group. Each group contains a set of one or more filters.

• The set of selected filters within each group forms an OR relationship between each other when more than one item is checked.
• The relationship between groups that have selected items will behave as an AND relationship in the query results.
• An example where letters represent groups and numbers represent items within the group.

  (A1 OR A3 OR A4 OR A12) AND (C3 OR C7 OR C30)

  This illustrates a selection from Groups A and C with nothing selected from B such that B's filters will NOT constrain the output.

• When no items are checked within one group, then that group will not be used as a filter, which will have an effect as if all items were checked. BUT...
• Selecting all items in a group that has more than 30 items IS NOT the same as selecting NO items in the group; any concept that is associated with with the 31st or greater item will NOT be included in the Search Results tab.
• By default, only the first 15 items are displayed in the group, sorted by the number of concepts associated with that item. Additional items can be displayed by clicking on the icon at the bottom of the group. A maximum of 30 items will be displayed. If there are more than 30 items in a group, they cannot be displayed; try applying filters in another group or the ALL category to reduce the number of items in any group that has more than 30 items.
• Example of selecting other facet item to reduce a group's items: Perform a text search on the gene apob and click Next to get to the Filter Results tab. Notice under Semantic Type there are about 16 items listed. Check the Disease category and then click on the All Categories under the pane Category Being Filtered to apply and update the selections. Notice how the Semantic Type group has been reduced down to 9 items.
• The result of applying the filters will impact the number of concepts that are presented on the Search Results tab. If item A3 had a count of 100 and item C7 had a count of 50, these total counts of how many concepts are returned depends upon the number of concepts that have a representation in both A3 AND C7. There does exist a probability that there are NO concepts that have both, and when such a condition occurs the results will be empty. There are also many concepts that have more than one possible filter for any given filter group. An example with the Semantic Type group is that some concepts may be associated with more than one semantic type.
• To see how the selection of various filters will impact the Text Search Results, just click on the currently selected category in the Category Being Filtered pane which will refresh the facets and their estimated totals.

• There does exist some filter groups where the total number of concepts that are represented in that group is far less than the number of concepts that would be returned by the search if no filter items in the group are selected. This is normal and due to the wide range of data that is included in Gataca. For example: A search on "APOB" will result in about 9 concepts in the Gene category, but only 7 have entries for their respective Chromosome filter. This difference is due to multiple data sources contributing to the Gene category and at least one of those sources do not identify this information.
• If a Category Being Filtered does not list any groups, it may be attributed to no results based upon the search term, or filter(s) set at the ALL category level is blocking any results for another category. An example would be a search on "APOB" and then at the ALL category level setting a Group filter on Disease. Then when you click on the Anatomy category under the Category Being Filtered pane you will see no results. This is due to the setting of filters only for diseases and hence any other categories, such as anatomy, will have no concepts associated with them.
• Remember the filter groups and filter items that are displayed represents the actual search results with all prior filters applied.

The text search results are now displayed in the appropriate category panes. If a category does not include any search results, it will will automatically be collapsed.
