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 meaning.
Code words in text, folder names, filenames, file extensions, pathnames, dummy URLs, and user input are shown as follows:
The field definition entry in the solrconfig.xml file tells Solr to look for all the JAR files from the ../../lib directory.
A block of code is set as follows:
<field name="id" type="string" indexed="true" stored="true" required="true" /> <field name="title" type="text" indexed="true" stored="true" /> <field name="author" type="string" indexed="true" stored="true"/>
When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:
<entry>
<name>documentCache</name>
<class>org.apache.solr.search.LRUCache</class>
<version>1.0</version>
