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.  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.  90  IBM Watson Content Analytics: Discovering Actionable Insight from Your Content Figure 5-4 Search fields and controls Search box and controls
