Assumption:  This chapter was written with the understanding that security is not enabled on the content analytics collection. 

Knowledge Center: By default, the IBM Content Analytics Information Center on the Content Analytics server starts when you start the Content Analytics server by using the esadmin system startall  command. 

## Search box and controls 

The search box under the application toolbar is used to find, mine, and filter documents based on your queries. Content Analytics contains a fully functioned search engine that is both scalable and fast so that you can explore your data by using conventional search methods. 

By default, the search box is hidden. After you either click the Show query input area  button or the Expand query input area  twisty, you will see the search box dialog (as in Figure 5-4). You can modify the query that is used for your analysis from this field.

When expanded, the current query is displayed in the search box dialog. Each addition to your search condition is appended to the query. At any time, you can save your current query state by clicking the Saved Searches  tab. After giving your query a name and saving it, you can return to that state by clicking the Saved Searches tab and selecting any previously saved queries. 

You can use the Advanced Search  tab to assist in the formulation of your search expression. By using the Advanced Search tab, you can specify complex search options, such as an exact phrase search or a search on date ranges, without knowing the Content Analytics query syntax. 

A graphical layout of your query is displayed when you click the Query Tree  tab. 

For more information about these tabs, see the section 5.2.6, “Saved searches” on page 105, section 5.2.7, “Advanced search” on page 107, and section 5.3, “Query Tree” on page 107.
