Tips from Sony Thomas

Read more about the search indexing @  http://tips4ufromsony.blogspot.com/2011/11/atg-search-architectural-flow-search.html ATG search indexing involves index file creation, deploying and copying the index file to the search engine's box. The steps can be divided into Initial stage, Preparing Content, Indexing and Deploying. Please find below the detailed analysis of each step. 1. Initial stage:        a. Check whether the folder deployshare configured correctly @ LaunchingService.deployShare  ( \atg\search\routing\LaunchingService.deployShare ). Lets assume that it is configured to \Search2007.1\SearchEngine\i686-win32-vc71\buildedIndexFiles.        b. Lets assume that the index file folder ( \Search2007.1\SearchEngine\i686-win32-vc71\indexFiles)  has the following segments (folders) currently :                     66900...

Here I am listing some erroneous cases that might occur in your web development phase, due to some size restrictions. JSP file size limit : You might get some run time exceptions that the JSP file size limit exceeds. Please find below the reason : In JVM the size of a single JAVA method is limited to 64kb. When the jsp file is converted to Servlet, if the jspservice method's size exceeds the 64kb limit, this exception will occur. Keep in mind that this exception depends on the implementation of the JSP translator, means the same JSP code may give an exception in Tomcat and may run successfully in Weblogic due to the the difference in the logic to built the Servlet methods from JSP. The best way to omit this issue is by using dynamic include.For example, if you are using                  <%@ include file="sample.jsp" %> (static include),  replace this to               ...

I would like to explain the high level ATG Search implementation architecture ( for an online store) through the above diagram. In this diagram 1.x denotes the search functionality and 2.x denotes the indexing functionality. I have given JBoss as the application server. Physical Boxes and Application Servers in the diagram ( as recommended by ATG )  : Estore ( Commerce ) Box --> The box with the estore/site ear (with the site JSPs and Java codes). Search Engine Box --> The box with the search engine application running. Indexing Engine Box --> The box with the indexing engine application running. CA (Content Administration) Box --> The box with the ATG CA ear ( where we could take CA -BCC - Search Administration and configure the search projects) . Search Indexer Box --> The box with the ATG Search Index ear ( to fetch the index data from repository). Note that the engine performing indexing will need access ...

If your browser is having a large number of extensions/add-ons, how can you ensure a secure e-banking ? Chrome incognito window or IE / Mozilla private browsing is the best option you have, to do the e-banking. Google Chrome does not control how extensions handle your personal data. But all the extensions have been disabled for incognito windows. (You can reenable them individually in the extensions manager ). The simplest way to start Chrome in Incognito @ Windows 7 is to right-click on its taskbar icon . Also think about the other uses of Chromey incognito, just like to use it for Guest account log-ins ...

Read the Eclipse Galileo features @  http://tips4ufromsony.blogspot.com/2011/10/good-features-of-eclipse35-eclipse.html New options in Open Resource dialog : The Open Resource dialog supports three new features: • Path patterns: If the pattern contains a /, the part before the last / is used to match a path in the workspace: • Relative paths: For example, "./T" matches all files starting with T in the folder of the active editor or selection: • Closer items on top: If the pattern matches many files with the same name, the files that are closer to the currently edited or selected resource are shown on top of the matching items list. MarketPlace :  Searching and adding new plugins for Eclipse have always been a challenge.

Have you got your Income Tax filing e-receipt ? After a successful assessment of tax returns, income tax department issues Intimation u/s 143(1). Normally these intimations will be received through email to the Email address provided when filing income tax returns online. If “NET AMOUNT REFUNDABLE /NET AMOUNT DEMAND”  is less than Rs 100, you can treat this Intimation u/s 143(1) as completion of income tax returns assessment under Income Tax Act. It can be useful for the proof of Income/ Completion of income tax returns assessment. In case of demand , we need to pay the entire Demand within 30 days of receipt of this intimation.The payment can be made using the printed challan enclosed in the mail or you can go for online tax payment. The Tax Payment challan is enclosed if the Tax Payable exceeds Rs. 100. If you go for online tax payment, follow the instructions listed @   http://tips4ufromsony.blogspot.com/2011/03/online-income-tax-payment-using.html  a...

Please find below the Lucene sample JAVA code to search the files inside a folder. This code will search the indexed folder for a search query in an indexed field. This java code is expecting the index path ( where the index files were created ) , field which need to be searched and the query need be searched as program arguments like  "java SearchFiles [-index dir] [-field f] [-query string]" . import java.io.File; import java.util.ArrayList; import org.apache.lucene.analysis.Analyzer; import org.apache.lucene.analysis.standard.StandardAnalyzer; import org.apache.lucene.document.Document; import org.apache.lucene.queryParser.QueryParser; import org.apache.lucene.search.IndexSearcher; import org.apache.lucene.search.Query; import org.apache.lucene.search.ScoreDoc; import org.apache.lucene.search.TopDocs; import org.apache.lucene.store.FSDirectory; import org.apache.lucene.util.Version; public class SearchFiles { public static void main(Stri...

Please find below the Lucene sample code to index the files inside a folder. This code will index ( or create fields for ) the file path, file title, modified date and contents of the file. This java code is expecting the index path ( where the index files will be created ) and file folder path as program arguments like  "java IndexFiles  [-index INDEX_PATH] [-docs DOCS_PATH]" . The logic of the code is to iterate through each file in the folder and call the method indexDoc(), where the above said fields are created and added to a Document object. This means that for each file there will be a document object and these document objects will be added to IndexWriter. Please find below the screen shot of the indexd file folder : import java.io.BufferedReader; import java.io.File; import java.io.FileInputStream; import java.io.IOException; import java.io.InputStreamReader; import java.util.Date; import org.apache.lucene.analysis.Analyzer; import org.apa...

Apache Lucene is a high-performance, full featured text search engine library written entirely in Java. It is part of Apache Jakarta Project. Lucene was originally written by Doug Cutting in Java. While suitable for any application which requires full text indexing and searching capability, Lucene has been widely recognized for its utility in the implementation of Internet search engines and local, single-site searching. Lucene is Doug Cutting’s wife’s middle name ! Features 1. Scalable, High-Performance Indexing Over 95GB/hour on modern hardware Small RAM requirements — only 1MB heap Incremental indexing as fast as batch indexing Index size roughly 20-30% the size of text indexed 2. Powerful, Accurate and Efficient Search Algorithms Ranked searching — best results returned first Sorting by any field Multiple-index searching with merged results Allows simultaneous update and searching 3. Flexible Queries Phrase queries –>  like “star wars” –> searc...

The ATG search  indexing will give you the idx and stg files. When I analyse the stg files with some text editors like Textpad or Ultraedit , found some <html> and </html> tags and the contents inside these tags seems to be the same content of the temporary XHTML files , which will be generated during the search indexing for each indexed item. So I deicded to take the contents in between the <html> and </html> tags and save as XHTML file and it works for almost all indexed items. As you might know, these XHTML file’s <head> tag contains all the meta properties ( refine properties ) and the <body> tag have the text properties ( searchable properties ) for each indexed item. Please note that the above steps are not an ATG recommended method to generate the XHTML files. I come across to this simple method to form the XHTML files and I am not 100% sure that this will give all the XHTML files of a search index . But I found this to be very useful f...
