+# Void Search
+
+Script for searching the structures in the CSD for void properties pre-calculated with PoreAnalyser. Can be run on the command line with:
+
+```python
+python void_search.py
+```
+
+or by launching from the CSD Python API dropdown in Mercury. If Launching from Mercury, put the script, with the accompanying search_result_template.html file, in your /mercury/scripts folder,
+or use the options dialog to "Add Location" to where you have saved the script. When the script is run, it will launch a dailog box with properties to search on, and spaces to fill in queries.
+These query boxes accept values like "200-300" or ">5" to constrain the search. A .tsv file is written with the search results, and the table is displayed in the Data Analysis tab; non-Ascii
+characters in chemical names will be deleted.
+A .gcd file of refcodes in the search results is also written, and read into Mercury
