This paper introduces a new Visualization technique "TileBars" for full Text Searches. Usually when a Boolean query is performed the output will be documents that contain the word and the ranking of documents in list depends on the frequency of word in that document. These documents are usually structured in the format as title, abstraction. The author says that the output should also contain the frequency and distribution of words in the document and the length of document. To serve this purpose TileBars can be used.This would help in analyzing the search results of Boolean type queries.The author introduces an algorithm called "TextTiling" to automatically determine the kind of document structure. The search results are displayed using rectangles and shaded squares indicating the length of document and subcategories of document and the shades denoting the frequency of word in that sub category. I find it as a very new and useful method of analyzing search results of Boolean queries and it also provides a compact view containing the document length, keyterm frequency and distribution.
