ProphetX news filters provides powerful filtering options to narrow your search for information.
You can save these filters and edit them as required to meet current needs. News filters can be anything from a simple keyword search to a collection of specific search statements. In addition, many news sources can only be accessed via a category code.
To open a Scrolling News Index
- Right-click in a news index and select Edit Index
- Use the line of text boxes to add search statements to your filter. Enter one line at a time as follows:
- Connector: Ignore this box for the first line. For the next line, click the arrow connected to this box and select AND or OR to begin your line. These are standard Boolean operators. AND will return titles only if the preceding line and this one are true (that is, the keyword or category selected is included in the news title). OR will return titles if either the preceding line or this one is true.
- Source: Click the drop-down arrow and select a news source for this line. You can search a different source for each line of a general news filter. To search the entire general news database, select the asterisk (*) at the top of this list.
- Type: Click the drop-down arrow and select a search type for this line — either Category or Keyword. Some news sources require a category code and others do not. Most of the time you will be searching for a keyword.
- Value: Type the specific category or keyword for the search, or click the drop-down arrow and select from those recently used. When entering keywords, searches are case sensitive. You can also include “wildcards” in your keywords.
When the line is complete, click the Add button to the right of it. To enter another line of search criteria, repeat the steps above for Type and Value, and click on Add..
Saving the Filter
- Click on the Add button at the bottom of the display.
Opening a Filtered index
- Locate it in the Files docked window pane.
- Double click on the filter name or icon or drag it to the ProphetX work area
Using Wild cards in News Filters
Entering soy as a keyword will return only headlines with the word “soy” in them. Use the following wildcards to expand the search.
Use a question mark to indicate any one character.
Examples:
soy??? will return soyoil, but not soy or soybean
soy???? will return soybean, but not soy or soyoil
Use an asterisk to indicate any number of characters, including none.
Example: soy* will return soy, soyoil, soymeal and soybean
