+## Helpers
+
+Going from a query to the combination of idents (with
+[esdump](https://github.com/miku/esdump), [jq](https://stedolan.github.io/jq/),
+[makecomb.py](https://gist.github.com/miku/c1220715060babc2374a440bd742a410):
+
+```
+$ esdump -q '"Calcifying+extracellular+mucus+substances"' | \
+    jq -rC '.hits.hits[]._id' | makecomb.py | awk '{print $1","$2}'

+Short script.
+
+```python
+#!/usr/bin/env python
+import fileinput
+import itertools
+
+vs = set()
+for line in fileinput.input():
+    line = line.strip()
+    if not line:
+        continue
+    vs.add(line)
+
+for a, b in itertools.combinations(sorted(vs), r=2):
+    print("{}\t{}".format(a, b))
