# Search

The search engine allows users to find topics using keyword-based queries. You can specify the proximity option, a search parameter which sets the number of words allowed between the query words in the results of the search. To perform search by keywords:

1. Enter keywords delimited by whitespaces into the Search Query field. If several words are entered, only the topics containing all of them (logical expression "and") will be displayed. For example, when the search query includes the keywords "adding content", only the topics containing both words, not only "adding" or "content", will be selected:
2. Select the addresses for search from the Addresses combobox. The default setting, "All Content", means that the keywords will be searched in the entire knowledge base content.
3. Specify the number of words that can separate the keywords found in topics. Several options are available in the Proximity Options combobox:
   - Anywhere means that the search will return topics each containing all the keywords. Keep in mind that if you are searching for a phrase and you have set the proximity option to Anywhere, you are very likely to get more results than if you select Phrase, because the result list will display the topics that contain all your keywords no matter in what order they appear. All the hits will be highlighted in different colors.
   - Phrase option is used when you conduct a search for a phrase. The hits will include only the topics containing the given phrase, i.e. the keywords in topics appear in the same order and are not separated by other words or symbols.
   - Words option is used when you are searching for an approximate phrase. The default proximity sets the default number of words that can separate the keywords in topic content. This number is shown in the entry field located to the right of the "Proximity Options" combobox. When you select Words, this entry field becomes active and you can change its value.
4. After you have specified all these parameters, click the Search button. The list of topics matching the search criteria will appear in the Found Topics listbox.
5. When you select some topic, its content is displayed in the right pane. In the displayed topic, the matches are highlighted in different colors: the first match - in yellow, the second - in blue, the third - in green, and so on.
6. If you want to see where the found topic is located in the Table of Contents, use the TOC Sync button - it will position the Table of Contents to the topic currently displayed in the Topic pane.
