What this doc covers
- What Phrase filters are and how they work
- Using 'Phrase Filters' to find specific results, in this case filtering by a foreign company suffix
In this simple example, we'll demonstrate a company discovery search that helps find relevant companies incorporated in the Germany (and a few nearby countries) via Phrase Filters. This example will use the fact that companies incorporated in these locations have a suffix of GmbH, which is a term in the region similar to the US 'incorporated'.
How Phrase Filters work
Exa's search combines semantic relevance with precise filtering: a neural query first retrieves contextually relevant documents, then a phrase filter refines these results by checking for specific text in the content. This two-stage approach delivers highly targeted outputs by leveraging both semantic understanding and exact text matching.
Running a query with phrase filter
Using Phrase Filters is super simple. As usual, install the exa_py library with pip install exa_py. Then instantiate the library:
# Now, import the Exa class and pass your API key to it.
from exa_py import Exa
my_exa_api_key = "YOUR_API_KEY_HERE"
exa = Exa(my_exa_api_key)
Make a query, in this example searching for the most innovative climate tech companies. To use Phrase Filters, specify a string corresponding to the includeText input parameter
result = exa.search_and_contents(
"Here is an innovative climate technology company",
type="neural",
use_autoprompt=True,
num_results=10,
text=True,
include_text=["GmbH"]
)
print(result)

"text": "Mehr Wachstum. Echter Klimaschutz. bionero ist eines der ersten Unternehmen weltweit, das zertifiziert klimapositiv arbeitet. Das Familienunternehmen, das in der Nähe von Bayreuth beheimatet ist, stellt qualitativ höchstwertige Erden und Substrate her, die durch das einzigartige Produktionsverfahren aktiv CO2 aus der Atmosphäre entziehen und gleichzeitig enorm fruchtbar sind. Aus Liebe und der Ehrfurcht zur Natur entwickelte bionero ein hochmodernes, industrialisiertes Verfahren, das aus biogenen Reststoffen eine höchstwertige Pflanzenkohle herstellt und zu fruchtbaren Schwarzerden made in Germany verwandelt. Hier kannst du bionero im Einzelhandel finden Wir liefern Gutes aus der Natur, für die Natur. Terra Preta (portugiesisch für \"Schwarze Erde\") gilt als \"wiederentdeckte Wundererde\". Sie wurde vor circa 40 Jahren in den Tiefen des Amazonasgebiets entdeckt und intensiv erforscht. Das Besondere an ihr ist ihre Fruchtbarkeit. Tatsächlich gilt dieser Boden als der fruchtbarste unseres Planeten. bionero hat gemeinsam mit Professor Bruno Glaser, einem weltweit anerkannten Experten für Terra Preta, das Herstellungsverfahren dieser besonderen Erde transformiert, optimiert und industrialisiert. Der wesentliche Wirk- und Inhaltsstoff ist eine sog. Pflanzenkohle. Sie sorgt dank ihrer enorm großen spezifischen Oberfläche für optimale Nährstoff- und Wasserspeicherfähigkeiten im Boden und bietet zusätzlich Lebensraum für wertvolle Mikroorganismen. Das Ergebnis ist ein stetiger Humusaufbau und eine dauerhafte Bodenfruchtbarkeit. Das Einzigartige an bionero? Die bionero Wertschöpfungskette ist vollständig klimapositiv! bioneros Produkte bieten einer Branche, die stark in die Kritik geraten ist, einen Weg in eine nachhaltige Zukunft. Während der Herstellung unserer hochwertigen Terra Preta leisten wir einen aktiven Beitrag zum Klimaschutz. Durch die Produktion unserer wichtigsten Zutat, der Pflanzenkohle, wird dem atmosphärischen Kohlenstoffkreislauf aktiv Kohlenstoff entzogen. Der Kohlenstoff, welcher anfangs in den biogenen Reststoffen gespeichert war, wird während des Pyrolyseprozesses für mehrere Jahrtausende in der Pflanzenkohle fixiert und gelangt somit nicht als Kohlenstoffdioxid zurück in unsere Atmosphäre. Das Erstaunliche: Die Pflanzenkohle entzieht der Atmosphäre das bis zu dreieinhalbfache ihres Eigengewichts an CO2! Die entstandenen Kohlenstoffsenken sind dabei transparent quantifizierbar und zertifiziert. Tatsächlich vereint bionero als erstes Unternehmen weltweit alle notwendigen Verfahrensschritte zu einer echten Kohlenstoffsenke gemäß EBC. Der Kohlenstoff ist am Ende der bionero Wertschöpfungskette in einer stabilen Matrix fixiert. Torf ist bis heute der meistgenutzte Rohstoff bei der Herstellung von Pflanzsubstraten. Schon beim Abbau werden Unmengen an CO2 freigesetzt. Moore sind einer der wichtigsten Kohlenstoff-Speicher unseres Planeten. Moore speichern 700 Tonnen Kohlenstoff je Hektar, sechsmal mehr als ein Hektar Wald! Durch die Trockenlegung und den Abbau für die Gewinnung von Torf können diese gewaltigen Mengen Kohlenstoff wieder zu CO2-reagieren und gelangen in die Atmosphäre. Hinzu kommen enorm weite Transportwege. Der Torfabbau findet zu großen Teilen in Osteuropa statt. Um einerseits die natürlichen Ökosysteme zu schützen und andererseits lange Transportwege zu vermeiden, setzen wir auf regional anfallende Roh- und Reststoffe. In langen Reifeprozessen verarbeiten wir natürliche Reststoffe zu hochwertigen Ausgangsstoffen für unsere Produkte. Bei der Auswahl aller Inputstoffe schauen wir genau hin und arbeiten nach dem Prinzip “regional, nachhaltig, umwelt- und klimaschonend“. Nur, wenn diese Voraussetzungen ausnahmslos gewährleistet sind, findet ein Rohstoff letztlich seinen Weg in unsere Produkte. bionero - Mehr Wachstum. Echter Klimaschutz. Erhalte spannende Einblicke in die Abläufe unseres Start-Ups und unsere hochmodernen Verfahren. Hier gibt es die neuesten Trends, aktuelle Tipps, hilfreiche Pflanz- und Pflegeanleitungen und interessante Videos."

In March 2014, Green City Solutions GmbH was founded by Peter Sänger and his friend Liang Wu in Dresden. They set up a team of young experts from the fields of horticulture/biology, computer science, architecture, and mechanical engineering. The knowledge of the individuals was bundled to realise a device that combines nature and technology: the CityTree.\n\nThe living heart of CityTrees is moss cultivated on hanging textile mats. The moss mats are hidden behind wooden bars that provide sufficient shade for these plants, which naturally grow mainly in forests. Sensors are measuring various parameters such as temperature, humidity, and concentration of particulates. This data is used to regulate ventilation and irrigation. Behind the moss mats are large vents that create an airflow through the moss. In this way, the amount of air cleaned by the device can be increased when pollution levels are high, such as during rush hours.\n\nGreen City Solutions collaborates with several partners in Germany and abroad. Scientific partners include the Leibniz Institute for Tropospheric Research (TROPOS) and the Dresden University of Applied Sciences (HTW Dresden), both located in Germany. Green City Solutions has been awarded the Seal of Excellence by the European Commission. This is a European Union quality label for outstanding ideas worthy of funding.\n\nThe work of Green City Solutions mainly contributes to the Sustainable Development Goals 3, 11, 13, and 15:"
