ENTERPRISE SEARCH TECHNOLOGY USING SOLR AND CLOUD By Padmavathy Ravikumar Masters Project Submitted in partial fulfillment of the requirements For the Degree of Master of Science, With a Major in Computer Science Governors State University University Park, IL 60484 Fall 2014 ENTERPRISE SEARCH TECHNOLOGY USING SOLR AND CLOUD 2 Abstract Solr is the popular, blazing fast open source enterprise search platform from the Apache Lucene project. Its major features include powerful full-text search, hit highlighting, faceted search, near real-time indexing, dynamic clustering, database in9tegration, rich document (e.g., Word, PDF) handling, and geospatial search. Solr is highly reliable, scalable and fault tolerant, providing distributed indexing, replication and load-balanced querying, automated failover and recovery, centralized configuration and more. Solr powers the search and navigation features of many of the world's largest internet sites. Databases and Solr have complementary strengths and weaknesses. SQL supports very simple wildcard-based text search with some simple normalization like matching upper case to lower case. The problem is that these are full table scans. In Solr all searchable words are stored in an "inverse index", which searches orders of magnitude faster. Solr is a standalone/cloud enterprise search server with a REST-like API. You put documents in it (called "indexing") via XML, JSON, CSV or binary over HTTP. You query it via HTTP GET and receive XML, JSON, CSV or binary results. The project will be implemented using Amazon/Azure cloud, Apache Solr, Windows/Linux, MS-SQL server and open source tools.

  • Final Report CS 5604: Information Storage and Retrieval
    Final Report CS 5604: Information Storage and Retrieval Solr Team Abhinav Kumar, Anand Bangad, Jeff Robertson, Mohit Garg, Shreyas Ramesh, Siyu Mi, Xinyue Wang, Yu Wang January 16, 2018 Instructed by Professor Edward A. Fox Virginia Polytechnic Institute and State University Blacksburg, VA 24061 1 Abstract The Digital Library Research Laboratory (DLRL) has collected over 1.5 billion tweets and millions of webpages for the Integrated Digital Event Archiving and Library (IDEAL) and Global Event Trend Archive Research (GETAR) projects [6]. We are using a 21 node Cloudera Hadoop cluster to store and retrieve this information. One goal of this project is to expand the data collection to include more web archives and geospatial data beyond what previously had been collected. Another important part in this project is optimizing the current system to analyze and allow access to the new data. To accomplish these goals, this project is separated into 6 parts with corresponding teams: Classification (CLA), Collection Management Tweets (CMT), Collection Management Webpages (CMW), Clustering and Topic Analysis (CTA), Front-end (FE), and SOLR. This report describes the work completed by the SOLR team which improves the current searching and storage system. We include the general architecture and an overview of the current system. We present the part that Solr plays within the whole system with more detail. We talk about our goals, procedures, and conclusions on the improvements we made to the current Solr system. This report also describes how we coordinate with other teams to accomplish the project at a higher level. Additionally, we provide manuals for future readers who might need to replicate our experiments.

Scholtes, Ph.D. Chief Strategy Officer, ZyLAB Contents Summary 3 Finding Without Knowing Exactly What to Look For 4 Beyond the Google Standard 4 Challenges Facing Text Analysis 6 Control of Unstructured Information 6 Different Levels of Semantic Information Extraction 7 Co-reference and Anaphora Resolution 11 Faceted Search and Information Visualization 12 Text Analysis on Non-English Documents 15 Content Analytics on Multimedia Files: Audio Search 16 A Prosperous Future for Text Analysis 17 About ZyLAB 19 Summary Text and content analysis differs from traditional search in that, whereas search requires a user to know what he or she is looking for, text analysis attempts to discover information in a pattern that is not known before- hand. One of the most compelling differences with regular (web) search is that typical search engines are optimized to find only the most relevant documents; they are not optimized to find all relevant documents. The majority of commonly-used search tools are built to retrieve only the most popular hits—which simply doesn’t meet the demands of exploratory legal search. This whitepaper will lead the reader beyond the Google standard, explore the limitations and possibilities of text analysis technology and show how text analysis becomes an essential tool to help process and analyze to- day’s enormous amounts of enterprise information in a timely fashion. 3 Finding Without Knowing Exactly What to Look For In general, text analysis refers to the process of extracting interesting and non-trivial information and knowledge from unstructured text.
