* Determined an R package to use for testing: testthat [[https://cran.r-project.org/web/packages/testthat/index.html]]
* Determined an R package to use for argument checks: checkmate [[https://cran.r-project.org/web/packages/checkmate/index.html]]
* Developed code samples that would be helpful during implementation
* Made further modifications to query structure 
== Coding Week 1: May 23-May 29 ==
* Determined package structure: Access to Xapian functionalities will be supported via three main wrappers: DatabaseWrapper, IndexingWrapper, SearchWrapper [[BR]]
* Developed the basic structure of IndexingWrapper (xapian_index() function accepts a data frame and a number of other compulsory and optional data structures as input arguments. In implementing the indexing function, each row in the data frame is considered a Xapian::Document.)
* Exposed the following Xapian functions and constructors in the form of input parameters to xapian_index() function or used internally within it:
 * Xapian::WritableDatabase -New, replace_document
 * Xapian::Termgenerator - New, set_stemmer, set_stemming_strategy, set_document, index_text(with prefix),index_text(without prefix), increase_termpos
 * Xapian::Document - New, set_data, add_boolean_term
== Coding Week 2: May 30-June 5 ==
* Completely facilitated simple indexing with xapian_index() function
* Verified the indexing functionality using the search and search_filters examples in Xapian C++ bindings
* Developed DatabaseWrapper
* Implemented the following functions: 
  * Xapian::Database - New, get_description, has_positions, get_doccount, get_lastdocid, get_avlength, get_doclength_lower_bound, 	get_doclength_upper_bound, get_uuid, get_metadata, get_spelling_suggestion, term_exists, get_collection_freq, get_value_freq, get_value_lower_bound, get_value_upper_bound 
== Coding Week 3: June 6-June 12 ==
* Added function documentation with roxygen2
* Developed SearchWrapper
* Exposed the following Xapian functions and constructors in the form of input parameters to xapian_search function or used internally within it:
 * Xapian::Query - New 
 * Xapian::QueryParser - New, set_stemmer, set_stemming_strategy, add_prefix, parse_query
 * Xapian::Enquire - New, set_query, get_mset
 * Xapian::MSet - New
 * Xapian::MSetIterator - New, get_document
== Coding Week 4: June 13-June 19 ==
* Modified the implementation of xapian_search
* Added tests for simple indexing and search with testthat R package
* Documented simple indexing and search
== Coding Week 5: June 20-June 26 ==
* Added code to handle valueSlots parameter in IndexingWrapper
* Designed advanced query structure
* Resolved some issues in package repository
== Coding Week 6: June 27-July 3 (Midterm deadline June 27) ==
* Implemented xapian_delete
* Added advanced indexing examples - Verified the indexing functionality using the search facets and search_ranges examples in xapian C++ bindings
* Started implementing advanced search features
== Coding Week 7: July 4-July 10 ==
* Supported faceted search via xapian_search function
* Continued to implement remaining advanced search features
== Coding Week 8: July 11-July 17 ==
* Completely supported 'range' queries via xapian_search function 
* Had mid semester exams this week 
== Coding Week 9: July 18-July 24 ==
* Completed advanced query implementation
* Modified the implementation of faceted search
* Developed R examples corresponding to index_ranges,index_facets,search_filters and search_facets examples in the Getting started guide with Xapian.
* Added automated tests 
== Coding Week 10: July 25-July 31 ==
* Supported ordering of search results 
* Added automated tests to verify that search results can be sorted
* Completed package documentation
* Modified package to remove NOTES and Warnings with R CMD Build
== Coding Week 11: August 1-August 7 ==
* Wrote some articles explaining the usage of RXapian functions
* Supported continuous integration with Travis-CI
* Added tests to check compatibility of range queries with Xapian version 
* Supported range queries for Xapian versions older than 1.3.6
== Coding Week 12: August 8-August 14 ==
* Resolved formatting issues
* Reimplemented xapian_delete to support document deletion by docid and by term
* Studied the structure of RcppBDT, Reddis
* Wrapped Database class with Rcpp Modules (note: this will not be directly useful for RXapian's functions)
