# Overview Page

The Search Optimizer Overview page provides statistics about the rules that you set up in IDOL Data Admin. You can use these statistics to help fine-tune your settings and monitor what your users see.

To open the Overview page, click Overview in the main navigation on the left of the page.

## Monitor Number of Searches

IDOL Data Admin tracks the total number of searches within the last 24 hours, yesterday, and in the last week. The Overview page also provides information on queries in those time periods that returned no hits, both as a percentage of the total number of searches, and in absolute terms.

## View Top Search Terms

You can view information on the top 10 most popular search terms in the last hour, day, or week. In the list of most popular search terms, you can click a linked term to run the search and view the results to help you to understand what the user actually sees. From the Search results page, you can:

- Promote documents or queries (see Promotions).
- Edit or add synonyms or blacklisted terms (see Keywords).
- View the unmodified results, without any promotions or keywords that you set up.

## View Zero Hit Terms

The Zero Hit Terms bar graph shows the number of searches that produced no results during the selected time period (in the last day, or in the last week). For the daily view, the searches are divided by hour, for the weekly view, by day. The graph also shows the total number of searches during the selected time period.

You can view information on the top 10 search terms that produced no results. In the list of terms, you can click a linked term to add synonyms for that search (see Synonyms). For example, if the search term city appears in the Zero Hit Terms list, you can create a synonym group for that term containing the terms metropolis and town. When users search again for the term city, instead of the search returning no hits, results that contain the terms metropolis and town are also included.

## View Top and Bottom Promotions

You can view details of the top promotions (that is, the promotions that performed best in the last hour, day, or week) and bottom promotions (that is, the least successful promotions in the last hour, day, or week). Click a promotion title to go to the Promotion Details page for that promotion, where you can fine-tune the criteria for the promotion. See Edit Promotions for more information.
