Review of the Basics... NewsRoom Search Tips
NewsRoom, with millions of stories from 6,500 different sources, is an unrivaled source of current information on virtually every subject. Take advantage of some of these tips to help you get exactly the news you need. Examples use DialogClassic and DataStarClassic command language.
| Restrict search to title, descriptors and lead paragraph |
When search terms appear in key sections such as title, descriptor or lead paragraph, it is usually a good indication that the story is very relevant.
|
DialogClassic Example:
?s optical (w) instruments/ti,de,lp
DataStarClassic Example:
1_:optical adj instruments.ti,de. |

| Increase precision with proximity connectors |
Searching for terms that appear close together is a good way to ensure that the terms are discussed in relation to one another in the story. Most useful are Dialog NEAR (n) and SAME PARAGRAPH (s) operators, and DataStar SAME SENTENCE (WITH) and SAME PARAGRAPH/FIELD (SAME) operators.
|
DialogClassic Example:
?s retina? (5n) scan?
?s biometrics (s) security
DataStarClassic Example:
1_:retina$1 with scan$4
1_:biometrics same security
|

| Use specialized subject indexing |
NewsRoom stories have been enhanced with indexes for Industry and Product Name, Event, Geographic Name and Company Name. Check the Dialog Bluesheet and DataStarDatasheet for field/paragraph labels. Use Dialog EXPAND or DataStar ..ROOT to view a list of index terms.
|
DialogClassic Example:
?expand pn=aerospace
?s gn=brazil
DataStarClassic Example:
1_:..root aerospace.ir.
1_:brazil.cn.
|

| Add special limit options |
You can use LIMIT options to focus your results. On DialogClassic, for example, use /LONG to narrow results to articles of more than 1,000 words, or /ENG to stories in English. Check the Dialog Bluesheet or DataStar Datasheet for a complete list of LIMIT options.
|
DialogClassic Example:
?s retina? (5n) scan?/long
DataStarClassic Example:
1_:retina$1 with scan$4
2_:1 and FULLTEXT=yes
|

| Review results with KWIC |
You can quickly review search results using the KWIC format to display 30 words of text around your search terms.
|
DialogClassic Example:
?type s1/kwic/1-20
DataStarClassic Example:
1_:..print 1 kwic 1-20
|

| Special note on Searching Author Name on Dialog |
Author Name in NewsRoom is a word-indexed field. To search an author name, you must use the field label AU= with the last name and first name with a connector and parentheses.
|
DialogClassic Example:
?s au=(barlow(2n)matt)
DataStarClassic Example:
1_:barlow with matt.au.
