Conventions

In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meanings.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "The mergeFactor class controls how many segments a Lucene index is allowed to have before it is coalesced into one segment."

A block of code is set as follows:

//Create collection of documents to add to Solr server SolrInputDocument doc1 = new SolrInputDocument(); document.addField("id",1); document.addField("desc", "description text for doc 1");

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

//Create collection of documents to add to Solr server SolrInputDocument doc1 = new SolrInputDocument(); document.addField("id",1); document.addField("desc", "description text for doc 1");

Any command-line input or output is written as follows:

 java -jar post.jar *.xml 

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes, appear as follows: "In the index, we can see that the token Harry appears in both documents."
