Base Claim:
1. A method comprising: receiving text from a plurality of documents; for each document of the plurality of documents: segmenting the received text of the particular document of the plurality of documents to create a set of segments, each segment including two or more words; for each of at least a subset of the segments of the set of segments: calculating a document frequency statistic indicating a frequency of a particular segment of the at least a subset of the segments within the particular document of the plurality of documents; comparing the document frequency statistic indicating the frequency of the particular segment within the particular document to a frequency threshold; and determining if the particular segment is a segment of potential interest of the at least the subset of the segments of the set of segments based on the comparison of the document frequency statistic of the particular segment indicating the frequency of the particular segment within the particular document to the frequency threshold; and calculating a distance between the particular document of the plurality of documents and each of the other documents of the plurality of documents using a text metric; storing the received text, the segments of potential interest of each document, the distances, and the document frequency statistics in a search database; receiving a search query and performing a search on the received text of the plurality of documents to generate search results, the search results including at least a subset of documents of the plurality of documents; dividing the at least the subset of the documents of the plurality of documents of the search results between a first set and a guide set; for each of the documents of the first set, determining a closest document of the guide set using the distances for that particular document to create partitions of documents; for each partition of documents: retrieving the document frequency statistics of each segment of potential interest of each document in the particular partition of documents; selecting a predetermined number of segments of potential interest of the documents in the particular partition of documents based on a highest frequency statistic of the retrieved document frequency statistics; and determining a label for the particular partition of documents including at least one of the predetermined number of segments of potential interest of the documents in the particular partition of documents; and providing the labels for each partition for display.

Claim 8:
8. The method of claim 1 further comprising approximating a distance measure between two documents in the search results using a Dijkstra's algorithm.
