| 6 | Introduction |
|---|
| 7 | ------------ |
|---|
| 8 | |
|---|
| 9 | Apache Solr Extraction provides a means for extracting and indexing content contained in "rich" documents, such |
|---|
| 10 | as Microsoft Word, Adobe PDF, etc. (Each name is a trademark of their respective owners) This contrib module |
|---|
| 11 | uses Apache Tika to extract content and metadata from the files, which can then be indexed. For more information, |
|---|
| 12 | see http://wiki.apache.org/solr/ExtractingRequestHandler |
|---|
| 13 | |
|---|
| 14 | Getting Started |
|---|
| 15 | --------------- |
|---|
| 16 | You will need Solr up and running. Then, simply add the extraction JAR file, plus the Tika dependencies (in the ./lib folder) |
|---|
| 17 | to your Solr Home lib directory. See http://wiki.apache.org/solr/ExtractingRequestHandler for more details on hooking it in |
|---|
| 18 | and configuring. |
|---|
| 19 | |
|---|
| 20 | Tika Dependency |

| 30 | |
|---|
| 31 | ================== Release 3.6.0 ================== |
|---|
| 32 | |
|---|
| 33 | * SOLR-2346: Add a chance to set content encoding explicitly via content type of stream. |
|---|
| 34 | This is convenient when Tika's auto detector cannot detect encoding, especially |
|---|
| 35 | the text file is too short to detect encoding. (koji) |
|---|
| 36 | |
|---|
| 37 | * SOLR-2901: Upgrade Solr to Tika 1.0 (janhoy) |
|---|
| 38 | |
|---|
| 39 | * SOLR-3295: netcdf jar is excluded from the binary release (and disabled in ivy.xml) |
|---|
| 40 | because it requires java 6. If you want to parse this content and are willing to |
|---|
| 41 | use java 6, just add the jar. (rmuir) |
|---|
| 42 | |
